Authors: Wu Hao , Zheng Li-Xin 
Published: March 2020

Abstract
Carbon dioxide is the inevitable product of the use of fossil fuels and is the main cause of global warming. In 2018, global carbon dioxide emissions reached 33.89 billion tons. Under the Kyoto protocol, countries are taking measures to reduce carbon emissions. China has pledged to peak its carbon emissions by 2030 and will work hard to reach the peak as soon as possible. This paper studies the development trend of fossil energy and the development space of renewable energy in China under the constraint of carbon emission by using mathematical models from an empirical perspective, and briefly analyzes its feasibility, and obtained preliminary conclusions. By 2030, total energy consumption will increase by 34 percent, fossil energy by 17 percent and non-fossil energy by 116 percent, accounting for about 24.4 percent of total energy consumption. This paper will forecast the total energy consumption from 2019 to 2030 according to the calculation model.

Authors: Chen C. Q. , Zhang W. , Wu H.J. , Wang R. 
Published: March 2020

Abstract
Fiber can improve the bending strength of cement mortar or concrete due to its high toughness. The straw fiber, SF and PF with different properties were mixed into the mortar in the same proportion and different mixing processes to prepare mortar specimens, and the different types of fibers were mixed for the standard curing 7d and 28d. The mechanical properties of the test piece affected the change in this study. The results were showed as follows: the strength of the mortar with straw fiber was higher than that of the post-mixing method, and the flexural strength (referred to as FS) was increased by about 16.0%; the FS of the mortar after the SF was added by 9.7% higher than that of the first blending method, but the compressive strength(referred to as CS) of the first mixed mortar was higher than that of the post-mixing method 16.9%, indicating that the SF had a high modulus of elasticity, which could improve the CS; the growth trend between the FS and CS of the mortar were close with PF. Under the SF first mixing process, the CS was maximized, followed by the PF at the post-mixing method, and the worst was the post-mixing method of the straw fiber.

Experimental study on seismic behavior of recycled steel tubular columns
Authors: Ye Jianfeng , Luo Caisong , Chen Huayan 
Published: March 2020

Abstract
In order to study the seismic performance of recycled steel tubular columns, four round steel tube recycled concrete columns were designed and fabricated, and low-cycle reciprocating tests were carried out. Considering the two parameters of regenerative coarse aggregate replacement rate and axial compression ratio, the whole process and failure mode of the specimen were observed, and the hysteresis curve, skeleton curve and stiffness degradation of the specimen were analyzed. The experimental results show that the failure process and failure modes of the recycled steel tubular columns are similar to those of ordinary circular steel tubular columns. The main performance is the drum bending of the steel pipe at the root of the test piece; the hysteresis curve of the test piece is full, and the replacement ratio of coarse aggregate is opposite. The hysteresis curve of the specimen has little effect, and the axial compression ratio has a great influence on the shape of the hysteresis curve, the skeleton curve, and the stiffness degradation. The recycled steel tubular column has good seismic performance.

Abstract
Taking the Clean Development Mechanism (CDM) wind power project as an example, this paper analyses the impact of carbon trading on China’s renewable energy investment. Based on the data of Certified Emissions Reductions (CERs) price and the registered volume of CDM wind power projects in China from 2008 to 2015, the correlation between the investment decision of CDM wind power projects and the carbon trading price is tested. This paper also establishes a profitability evaluation model for CDM wind power projects, calculates the internal rate of return (IRR) of the projects, and uses the benchmark analysis method to evaluate the economic competitiveness and investment attractiveness of the projects with or without the income of CERs. Additionally the sensitivity analysis is conducted for the main investment and income variables. It is concluded that the investment decision of China’s CDM wind power project is closely related to the current carbon trading price, and the carbon trading income is the main method to improve the profitability of renewable energy projects.

Abstract
The thermo-sensitive hydrogel incorporating maleic anhydride modified mcirocrystalline cellulose was prepared by two steps. At first, the mixture of maleated and fumarated celluloses were produced by a solvent-free procedure, in which the biopolymer was added to molten maleic anhydride. Secondly, the photo-polymerization of n-isopropyl acrylamide (NIPAM) with the modified biopolymer was carried out in water/NaOH/urea/thiourea solution by using 1173 as the photo-initiator. The derivatives were characterized by FTIR and SEM. It was a clear temperature dependence on the volume of the grafted hydrogel in deionized water that generated by the coil-to-globule transition of poly (NIPAM) in aqueous media from the lower critical solution temperature (LCST) of PNIPAM to the upper critical solution temperature (UCST). From the absorbance of the gel to methylene blue, it was shown that the quasi-second-order kinetics could fit the experimental data well.

Authors: Liu Liang , Cao Jiahao , Xiang Xiwang , Zhang Peng 
Published: March 2020

Abstract
Energy is the cornerstone of social progress, and energy consumption is an important reference data when the government makes energy policies. Therefore, prediction of energy consumption can provide a basis for the formulation of policies. In the traditional grey system theory, the grey input is always regarded as an invariant after determined by the least square method. However, the grey input would be changed along with the change of the internal information in the grey system. As a result, the performance and accuracy of the grey model would be affected by it.Therefore, this paper proposes the ARIMA-b-GM (1,1) model, which uses the ARIMA prediction model to fit and predict the grey input and realize the dynamic change of the grey input. Then the time response sequence of the ARIMA-b-GM (1,1) model is deduced by changing the form of grey differential equation. Finally, the ARIMA-b-GM (1,1) model is applied to predict the per capita energy consumption in China. The results exhibit that ARIMA-b-GM (1,1) model has higher prediction accuracy than GM (1,1) model, NGM (1,1) model and SAIGM (1,1) model.

Published: March 2020

Abstract
High quality one-dimensional ZnO nanometer array (ZnO NAs) was synthesized by low-temperature hydrothermal method. The length and diameter of ZnO NAs was regulated by controlling hydrolysis time (Th) and the concentration of hydrolysate, and the surface was modified by aluminum-doped ZnO (AZO) to obtain ZnO/AZO core-shell nanometer array, which was used as the photoanode of dye-sensitized solar cells. The ZnO NAs provide a direct and stable channel for charge transfer. The electron recombination caused by reaction of the acid dye and ZnO photoanode have reduced as adding AZO shell, and increased the array surface roughness to improve the load of dye molecules. As a result, the DSSC of composite film has a hig power conversion efficiency of 1.75%.

Published: March 2020

Abstract
Cotton is an important economic crop, which plays an irreplaceable role in national production and life. With the economic development of society, the demand for cotton is also growing, which means that a lot of transportation and storage are needed. Cotton has the characteristics of smoldering, so in the process of transportation and storage, we should pay attention to the management of cotton. Open fire can cause the smoldering of cotton. In the wet environment, it is beneficial to the reproduction of microbes. If the heat can’t be released in time, it will also cause the smoldering. The density of cotton bags is different, and the porosity is different. The oxygen content in the cotton bag changes, which has an impact on the combustion state. Therefore, in this experiment, the test phenomena, quality changes and temperature changes after burning are studied for different density of cotton samples.

Published: March 2020

Abstract
This paper performs an ultrasonic-enhanced glucosinolate extraction test with the rapeseed cake as the object and ethanol as the solvent, and compares this method with the conventional one. Based on that, this paper studies the stability of glucosinolate. The result shows that under the optimal conditions (150W acoustic power, 70% ethanol, 4:1 (mL/g) liquid-to-material ratio, 60 °C, and the extraction frequency of 5 times/15 min), the glucosinolate yield can reach 62.1 mg/g. Compared with the conventional method, in order to reach the same yield, the method used in this paper can reduce the required temperature by 20 °C and shorten the extraction time by 40%. Stability test shows that the glucosinolate is sensitive to temperature and pH, more stable below 80 °C and in neutral environments; it degrades faster above 80 °C, and is easy to decompose in acidic and alkaline environments. Under the test conditions, its stability decreases with the increase of acoustical power.

Study on Denitration Performance of CeO2 Modified CuO/γ-Al2O3 Catalyst Under Deferent Flue Gas Components
Authors: Zhang Qi-Long , Dong Yong , Cui Lin 
Published: March 2020

Abstract
The effects of different flue gas components such as n(NH3)/n(NO) ratio, SO2 and H2O on the NO removing efficiency of Cu8Ce3 catalyst were studied in a fixed bed reactor. The experimental results show that the diffusion pressure and diffusion rate of NH3 in the catalyst microporous are the main factors affecting the NO removing efficiency, when n(NH3)/n(NO) ratio<1.05. The n(NH3)/n(NO) ratio no longer plays a decisive role in the denitration efficiency, when n(NH3)/n(NO) ratio >1.05. The effect of water vapor and SO2 on the denitration efficiency is different at 350°C and 400°C. The water vapor and NH3 have a competitive adsorption relationship on the catalyst surface, which reduces the adsorption of NH3 on the catalyst surface. This is the reason why the efficiency is suppressed at 350°C; the addition of water vapor can improve the surface acidity of the catalyst at 400°C, which is why the denitration efficiency is improved at this temperature. At 400°C, the adsorption rate of SO2 on the surface of Cu8Ce3 catalyst is higher than that at 350°C. As the temperature of flue gas increases, the adsorption amount of NH3 on the catalyst surface is reduced. This is why the denitration efficiency is depressed under the SO2 intervention. The adsorption and oxidation efficiency of NH3 in the sulfided catalyst at 400°C is improved, which is the main reason for the improvement of denitration efficiency at this temperature.

Authors: Chen Youliang , Geng Haitao , Zi Pingyang , Xu Ming , Fan Rong 
Published: March 2020

Abstract
Considering the effect of vacuum tightness on the performance of condensers, the influence of various operating parameters on condenser pressure and terminal difference was studied by establishing a calculation model of variable operating conditions of condensers. The results show that the change of heat load has a greater impact on the vacuum, and the effect is more pronounced when the initial temperature of the cooling water is higher. Therefore, it is necessary to strictly control the internal leakage of the valve, reasonably adjust the steam parameters of the shaft seal, and minimize the additional heat load on the condenser. The cooling water flow and initial temperature directly affect the condenser vacuum and have a greater impact. The initial temperature of the cooling water is not easy to control. When the initial temperature is high, most power plants use a method of increasing the flow to increase the condenser vacuum. The cleaning coefficient and air leakage have a great impact on the quality of the vacuum. Therefore, regular operation of the rubber ball cleaning system and timely vacuum leak detection are necessary measures to ensure the vacuum of the unit, which can effectively improve the economic efficiency of the unit.
