), instantaneous desorption rate (Vmax) and desorption kinetics. It was concluded that the maximum instantaneous desorption rate could better represent the desorption rate required by the experiment at different sweeping concentrations and temperatures. The maximum instantaneous desorption rate Vmax increased with the rising temperature and decreased with the increasing concentration of inlet methylene chloride. The concluded law was the same as the average desorption rate (

As the temperature increased, the concentration of inlet methylene chloride also inhibited the maximum instantaneous desorption rate Vmax more obviously. This provided important reference data for the optimization design of desorption equipment in the activated carbon adsorption process.

Effects of Compound Sweep and Lean on the Aerodynamic Performances of Transonic Centrifugal Impellers
Authors: Zhao Huijing , Lu Xiang , Zhao Guanhui , Ma Rui 
Published: July 2019

Abstract
The blade lean and sweep has a significant effect on the centrifugal compressors performance. This paper modifies the blade leading edges of two transonic centrifugal impellers with two compound sweep and lean (CSL) methods: the blade tip forward sweep with a negative lean (SFB), the blade tip backward sweep with a positive lean (SBB), and the CSL effects are numerically studied. For the unshrouded impeller, the SFB improves the highest isentropic efficiency and total pressure ratio. The SBB decreases the total pressure ratio and almost has no effect on the isentropic efficiency. The SFB expands the stall margin. Conversely, the SBB decreases the stall margin. The CSL effects on the shrouded impeller are less obvious compared with the unshrouded impeller. By analyzing the flow field, it is found that, the CSL has important effects on the shock, the accumulation of low momentum fluid and the blade loading near the blade leading edge for unshrouded impeller and shrouded impeller. Since the CSL effects on the stall margin of the unshrouded impeller are associated with the blade tip loading and tip clearance leakage flow, the CSL does not influence the stall margin of the shrouded impeller without a tip clearance.

Abstract
The alumina plant emits a large amount of production wastewater every day, which causes serious pollution to the environment and also seriously wastes water resources. In response to this problem, the electrodialysis method was used to treat and recycle the wastewater from the alumina plant. The test adopts cyclic desalination. The volume of fresh water controlled during the test is 4 times of the volume of concentrated water, that is, the recovery rate of wastewater is 80%. The constant pressure, constant current operation and the desalination effect of fresh water inlet line speed under constant pressure conditions are respectively carried out. the optimal operating conditions of the system was determined. Using 100 V terminal voltage to control fresh water and concentrated water inlet line speed of 5 cm / s, three parallel desalination tests were carried out. The results showed that the salt content of fresh water was less than 500 mg/L. and the water quality meets the industrial water requirements of the alumina plant. The energy consumption per unit of water production is relatively low, less than 1.75 kw·h/m3 fresh water, which is beneficial for economic development.

Stability Study of Poly Nitro Substituted Compounds of cis-syn-cis-2,6-Dioxodecahydro-lH,5H-Diimidazo[4,5-b:4’,5’-e] Pyrazine
Authors: Yang Tongtong , Xu Zhibin , Meng Zihui 
Published: July 2019

Abstract
Due to their excellent performance both in density and high detonation velocity, poly nitro substituted cis-syn-cis-2,6- dioxodecahydro-lH,5H-diimidazo [4,5-b:4’,5’-e] pyrazine derivatives (2-5) attract our focus. The stabilities study showed that the sensitivity of these compounds is increasing with more nitro groups substituted. Although compound 5 with six nitro groups exhibits the most excellent detonation velocity, it is very sensitive to friction and impact. As isomer to each other, compound 2 and 3 showed not only low sensitivity but also good thermal stability with similar detonation performance to RDX and HMX. It suggests that they are potential energetic materials.

A novel liquid precipitation route to synthesize high-quality cobalt carbonate with low chloride ions concentration
Authors: Guo Miaomiao , Xi Xiaoli , Li Sen , Long Xiaolin , Nie Zuoren , Xu Kaihua 
Published: July 2019

Abstract
Herein, high-quality cobalt carbonate is synthesized by employing a novel liquid phase precipitation route, where CoCl2 and ammonium bicarbonate solutions are used as the raw material and precipitator, respectively. The morphology of primary and secondary particles and agglomeration due to their nucleation and growth are influenced by the stirring speed, reaction temperature and pH value. Furthermore, the influence of process parameters on physiochemical properties has been systematically studied by measuring apparent density, FSSS particle size, specific surface area and chloride ions concentration. Under optimal processing conditions, i.e., stirring speed of 100 rpm, pH value of 7.0-7.1 and a reaction temperature of 55 °C, the as-synthesized cobalt carbonate rendered an apparent density of 0.74 g/cm3 and chloride ions concentration of 19 ppm. The results reveal that the washing efficiency of chloride ions is affected by the morphology of primary particles and stacking mode of the secondary particle in cobalt carbonate. In general, the higher BET specific surface area of cobalt carbonate results in lower chloride ions concentration.

Published: July 2019

Abstract
The correct identification of oil and gas reservoirs is very important in oil and gas field production. To solve the problem of oil and gas reservoir evaluation in low salinity and low porosity reservoirs, thermal neutron imaging system(TNIS) is introduced. The advantage of TNIS is that it can record a large number of formation information through multiple detectors to obtain imaging documents, allowing intuitive quantitative analysis of formation, and calculate oil and gas saturation through thermal neutron capture cross section, attenuation spectrum and capture spectrum, so as to obtain oil/gas/water distribution near wellbore. In the processing, interpretation and evaluation of thermal neutron imaging logging data, the interpretation model, parameters and criteria are established according to the geological characteristics of lithology and formation water salinity of the target block, which improves the interpretation coincidence rate. Field application shows that thermal neutron imaging logging has achieved sound effects in identifying watered-out zone, potential zone, gas reservoir and residual oil distribution monitoring.

Published: July 2019

Abstract
Aiming at the development status of Liuxi Oilfield, waterflood stimulation is studied to improve the development effect. The process is as follows: in begin with, the displacement liquid is injected into the oil well quickly to replenish energy; then the oil well is closed a while to promote oil and water displacement; finally, let the oil well produce under a reasonable system of production. Strong water-wet, high oil saturation, the degree of fracture development and low oil viscosity are the advantages of using waterflood stimulation by analyzing related researches. Based on the reservoir engineering research, numerical simulation method which is about waterflood stimulation is established using Eclipse software. According to the numerical simulation results, assuming that injection rounds is one time, when injection volume is more, the formation pressure rises higher and the liquid sweep is wider and cumulative production is more. At the same time, the degree of stage production is increasing with the closed time lengthen. But it has the most optimum values about the closed time, and the production increase of the degree of stage production becomes significantly slow.

Published: July 2019

Abstract
Desalination via hydrate processes is a novel and attractive method for desalting seawater. However, it is a great challenge to form hydrates with large amount in a short time, especially in the presence of high concentrations of salts. In this study, we used cheap and easily separated graphite particles to promote hydrate-based desalination. It was confirmed that graphite has no impact on the structures and compositions of cyclopentane hydrates. The dosage of used graphite can dramatically increase the conversion rate of water to hydrate, without degradation of the desalination efficiency. Due to the presence of graphite, the ratio of NaCl solution to cyclopentane has little impact on the conversion rate. A multi-stage desalination via hydrate formation was demonstrated, which can produce high quality freshwater with a purity of 99.76% meeting the drinking water standard. The findings in this study will help to rationally select and design the desalination process based on hydrates.
