title: DESIGN OF A REACTIVE DISTILLATION COLUMN FOR GLYCEROL ETHER PRODUCTION

description: Biodiesel, an important alternative energy, is generally produced from a transesterification reaction of vegetable oils and alcohol. This reaction always generates crude glycerol as by-product. As a result, the utilization of crude glycerol to produce higher value-added products can increase the competitive potential of biodiesel producers. In this research, the production of di and tri tert-butyl ether of glycerol (known as glycerol ether) from etherification of glycerol and tert-butyl alcohol is studied. Due to the nature of the reversible etherification reaction, a reactive distillation in which chemical reaction and separation can occur at the same time in single unit is considered to improve the glycerol ether production. Furthermore, since methanol is always present in crude glycerol, it is considered to be used for the production of dimethyl ether, a promising alternative fuel to replace diesel fuel and liquefied petroleum gas. This study is divided into three parts. In the first part, the effects of key design and operating parameters of the reactive distillation on the performance of glycerol ether production are studied. The results show that the use of the reactive distillation can increase the conversion of glycerol to glycerol ether into 99%. Based on a total annual cost analysis, the optimal configuration of reactive distillation column consists of 2 rectifying stages, 8 reactive stages and 1 stripping stages. In the second part, the application of a reactive distillation to the dimethyl ether production is investigated and the analysis of a total annual cost is used to design the reactive distillation column. The simulation results show that the reactive distillation can increase the conversion of methanol in crude glycerol to dimethyl ether into 99% and the optimal configuration of the reactive distillation column consists of 2 rectifying stages, 8 reactive stages and 2 stripping stages. As a separation of tert-butyl alcohol and water, which forms a azeotrope mixture is a difficult task, in the final part of the study, the use of a extractive distillation using different solvents, which are hexyl acetate, 2-heptanone and 3-octanone, for recovery of tert-butyl alcohol in the production process of glycerol ether is studied and compared in terms of the total annual cost and potential environmental impact as criteria. The results show that hexyl acetate is the most appropriate solvent.

title: CO2 REFORMING OF METHANE ON Ni, Co-CONTAINING Al2O3-H-BETA PREPARED BY SOL-GEL METHOD

description: In the present research, the effect of monometallic (10%wt.Ni, 10%wt.Co) and bimetallic (5%wt.NiCo) on different supports are H-Beta-Al2O3, Al2O3-SiO2 prepared by sol-gel method, and Gamma-alumina commercial catalysts. In addition, to study the effect of bimetallic catalysts with different loading ratio of nickel metal and cobalt metal on H-Beta-Al2O3 supports. Loading ratios of nickel and cobalt indicates as followed 1:3, 1:1, and 3:1. The catalytic activity tests for carbon dioxide reforming of methane at 700˚C and atmospheric pressure. It was found that the optimize bimetallic (5%wt.Ni5%wt.Co) which contained Ni:Co in a ratio of 1:1 supported on H-Beta-Al2O3 catalyst prepared by Sol-gel exhibit highest methane and carbon dioxide conversion in carbon dioxide reforming of methane reaction. The superior catalytic performance can be explain by the optimize amount of nickel and cobalt active sites and the smaller with NiO and CoO particles due to higher dispersion implied an easier reducibility and a shift the reduction temperature toward lower temperature. In Addition, the optimize cobalt addition which contained Ni:Co in a ratio of 1:1 has improving nickel metal dispersion of catalysts due to reduce the agglomerate of nickel particles. These features mirror a substantially higher resistance to carbon deposition of cobalt-containing catalysts.

title: DOPING OF CeO2 IN V2O5-TiO2 CATALYST FOR LOW-TEMPERATURE SELECTIVE CATALYTIC REDUCTION OF NITROGEN OXIDE BY AMMONIA

description: This research investigated the selective catalytic reduction of NO by NH3 over V2O5-CeO2/TiO2 catalyst at low temperature. Formation of nitrogen oxide from the ammonia oxidation reaction and SCR reaction was also investigated. Titanium dioxide support was prepared by a sol-gel method. Then vanadium and cerium were deposited via an incipient wetness impregnation method. The amounts of vanadium and cerium in the catalyst ranged from 1 to 7%wt and 5 to 30%wt, respectively. The catalysts were characterized by N2 physisorption, ICP-OES, XRD and NH3-TPD techniques. The testing of SCR activity of the catalyst was carried out in a tubular reactor at a temperature in the range of 120-450oC. From the result, the catalyst containing 5 %wt. V2O5, 30 %wt. CeO2 showed superior SCR activity at low temperature and reached the highest activity at 250oC. The addition of CeO2 increased the specific surface area and the total acid site of catalyst, resulting in high catalytic activity. The extent of ammonia oxidation increased as the reaction temperature and the vanadium content in catalysts increased. Addition of cerium to catalyst inhibited ammonia oxidation reaction and retained the SCR activity at high temperature. Furthermore, the addition of cerium oxide to the V2O5-TiO2 catalyst yielded SCR catalysts an excellent resist to water vapor and sulfur dioxide under our test conditions.

title: AN OVERBOOKING MODEL FOR AIR CARGO INDUSTRY

description: Overbooking is one of the most important techniques in revenue management which sells goods or services in excess of the available capacity because there is a possibility that some customers might cancel or not show up. In air cargo overbooking problem, overbooking model is more complex as compared to others because of the two-dimensional characteristic, i.e., weight and volume of the booking requests. This study presents two-dimensional air cargo overbooking models to find the optimal overbooking level with an objective of minimizing the total cost. Booking request and show-up rate are random variables with known distributions. This research proposes a new way of modeling the total cost that has not yet been presented before. There are four main parts in this research. First, the full mathematical model is formulated. Second, computational experiments are used to observe the impacts of important factors on the optimal overbooking level. Third, the other two models are proposed to reduce the complexity of the full model: 1) a regression model with interactions and 2) a naive method model. Last, the results of these three models are compared to identify which situation is suitable for each. The results showed that the optimal overbooking level obtained from the simplified regression model is close to the optimal overbooking level obtained from the full model (R-sq(adj) = 98.3%). The naive method is the simplest method presented in this study; however, it does not always give the appropriate optimal overbooking level. For example, the naive method predicts the optimal overbooking level close to the real optimal overbooking level when the ratio between the offloading and spoilage costs are low because it does not consider this factor.

title: MINIMIZING MAKESPAN USING NODE-BASED COINCIDENCE ALGORITHM IN THE PERMUTATION FLOWSHOP SCHEDULING PROBLEM

description: Scheduling problem has always been an important problem in the industrial sectors since it creates huge impact on the overall performance of the manufacturing. Good scheduling can reduce overall production time which then leads to lower cost and good resource management. The permutation flowshop scheduling (PFSP) is the classic scheduling problems that attracts both business and research area for almost half a century. On research side, a variety of complex algorithms have been introduced to solve the problems and provide high quality of solutions. Nevertheless, these algorithms will be useless if they fail to implement in practice where computational time and complexity of algorithm become an important issue of concern. This research proposes a Node-Based Coincidence Algorithm (NB-COIN) for the permutation flowshop scheduling problems (PFSP) aimed at Makespan minimization. NB-COIN is proved to be an effective algorithm that can provide good quality solutions using small amount of time and resources. The results generated by NB-COIN are also better than other well-known algorithms in consideration. Based on the bench-mark data sets of Taillard, 10% of the solutions provided by the presented algorithm are optimal solutions. Moreover, the solutions found by NB-COIN are also achieve 0.96% gap from upper bound in average. More importantly, those solutions are found within a short time.

title: Monitoring of the Sagaing fault in Myanmar using GPS observations

description: The objectives of the research were to analyze the Myanmar cGPS network observations to obtain a moving rate and direction of every cGPS point by using the GAMIT and GLOBK software package and to investigate the co-seismic moving rate due to the earthquake by using the TRACK kinematic processing program. The study observed four years of continuous GPS data between 2011 and 2014. It was found that the east side of the Sagaing fault the moving toward the southeast with the average rate of approximately 32-40 mm/yr and the other side of the fault the moving to the northeast with the rate of about 31-35 mm/yr. For the co-seismic study were observed at 2 stations of the Myanmar cGPS network, associated with the 2012 M6.8 Thebeikkyin earthquake. The GPS stations are located 50-60 km away from the epicenter. The GPS observation data clearly showed co-seismic ground displacements. According to the kinematic processing results, the GPS station from the east side of the Sagaing fault immediately moves to the southward, offset rate is 15 cm. Other side of the GPS station north offset is 3 cm. This study was compared the kinematic processing results for co-seismic movement rate and GAMIT/GLOBK time series results, which showed fairly good agreements. From this study, it can be concluded that the Sagaing fault using the GPS observation, the Sagaing fault’s tectonic activities can be monitored. This analysis method is useful in many ways to make a research on monitoring the Sagaing fault tectonic actives in Myanmar.

title: IMPACT OF CLIMATE CHANGE ON GROUNDWATER RECHARGE IN HO CHI MINH CITY AREA

description: Groundwater is very important for the development of Ho Chi Minh City since it provides 32% of water supply, however, the groundwater level is decreasing dramatically in recent years due to the socio-economical demand. Moreover, groundwater in Ho Chi Minh City is directly impacted by climate factors such as precipitation, evapotranspiration, and river water stage. However, the study of climate change impact on groundwater for the area is just in the starting stage. The study presented the application of groundwater model (MODFLOW) using Global Climate model (GCM) data to study the impact of climate change on groundwater recharge in the area. Global Climate Model (GCM) named MRI-AGCM3.2s is used to project precipitation and temperature for the area in two future timeframes, i.e., near future (2015-2039) and far future (2075-2099). Bias-correction method exhibited ability of reducing biases from the frequency and amount when compared with observed and computed values at grid nodes; based on spatially interpolated observed rainfall data. Groundwater model is applied to estimate historical recharge rate (1995-2007) and develop recharge function as well as groundwater simulation, to determine the impacts of climate towards groundwater recharge. Calibration groundwater model is implemented during 1995-2007 and verification groundwater model during 2008-2012. Calibrating and verifying groundwater model show that the simulation result is more reasonable when using recharge rate function with effective rainfall and with the recharge function, the impact of climate factor such as precipitation and temperature on groundwater recharge can be examined in the future. Two cases of future groundwater simulation were conducted such as with/without sea level rise to assess the impacts. As a result, future groundwater simulations show that groundwater resources in the area will be impacted by climate change and sea level rise. Groundwater recharge from land surface will decrease 17% in the near future due to more evapotranspiration and recover in the far future period due to more precipitation. Besides, climate change and sea level rise will increase groundwater level in the future, however, it also leads to the increase possibility of salt water intrusion in the same time. For groundwater management improvement, this study simulated future groundwater conditions by controlling groundwater pumping. The results show that groundwater pumping reduction of 41% in the near future and 56% in the far future can make groundwater level increase 2.86 m in the near future period and 4.56 m in the far future period, and decrease 41% and 56% of salt water flow from salt water zone to fresh water zone in near future and far future, respectively.

title: EFFECTS OF CASTING DIRECTION ON PUNCHING SHEAR STRENGTH OF ULTRA HIGH PERFORMANCE FIBER REINFORCED CONCRETE SLABS

description: Punching shear, characterized by a brittle behavior, which is considered as the typical failure mode of slab structures. Recently, Ultra High Performance Steel Fiber Reinforced Concrete (UHPFRC) has been known as a new achievement in concrete technology with much superiority mechanical properties which can help people to deal with the problem of punching shear of the thin slab. For UHPFRC material, the properties before and post-cracking mainly depend on the orientation of the fibers, which much depends on the casting method. In this research, an experimental work was conducted on 8 square UHPFRC slabs to investigate the effects of casting direction on punching shear capacity and modify an equation to predict the punching shear strength. The main parameters among these specimens were fibers volume fraction and different casting positions. The results showed that increasing fibers volume can significantly increase the ultimate punching failure load as well as delay the appearance of first cracks. Fibers also change the failure mode of the UHPFRC slabs from brittle to more ductile behavior. The more fibers the less flexural cracks were created and the higher ultimate punching shear failure loads were obtained. The effects of casting direction were clearly illustrated based on the size of failure cone. The slabs with the random distribution of fibers have smaller failure cone while comparing to slabs with the deliberate distribution of fibers. The results from the test and literature review were used to formulate an equation for predicting the punching shear capacity of UHPFRC slabs which gave the good agreement with the experimental results in this study.

title: RELIABLE SYNTHESIS AND MANIPULATION OF SELF-RUNNING GALLIUM DROPLETS ON GALLIUM ARSENIDE (001) IN MBE

description: A procedure for reliable synthesis and the attempts to manipulate self-running Ga droplets on GaAs (001) in a molecular beam epitaxial (MBE) machine have been investigated. The running Ga droplets are studied by atomic force microscopy, differential interference contrast microscopy, and scanning electron microscopy. Their electrical properties are characterized by current-voltage (I-V) measurements. Using the proposed procedure, the formation of self-running Ga droplets has been reliably achieved in MBE despite the lack of real-space and real-time imaging capability. The procedure is based on the observation of in situ reflection high-energy electron diffraction patterns and the registration of an appropriate reference temperature followed by controlled sublimation profiles. The Ga droplet-GaAs interface is probed electrically; preliminary I-V measurements indicate that the interface shows a Schottky behavior. The manipulation of self-running Ga droplets migration using buried defects is proposed and demonstrated in a low-energy electron microscope. The Ga droplets are found to run and take sharp turns upon meeting with defects, possibly from Ga-spitting. Such results provide new insights of the running droplets dynamics and may open up opportunities to steer the droplets motion.
