Abstract ：
Acquiring value-added chemicals from renewable ethanol instead of fossil resources has special significance under the background of carbon neutrality. In this work, a heterogeneous recyclable biomass-derived Ni/bio-apatite catalyst was developed for upgrading ethanol to higher alcohols (C6+-OH). Catalysts were prepared employing calcined porous natural bone and analyzed by various characterizations of thermogravimetric analysis-differential thermal analysis, X-ray diffraction, high-angle annular dark field scanning transmission electron microscopy, X-ray photoelectron spectroscopy, H-2-temperature-programmed reduction, and CO2-temperature-programmed desorption. The ethanol upgrading reaction can be achieved in the liquid phase without alkali additives, ligands, and extra hydrogen. The selectivity for C6+-OH reached as high as 67.7% at the single pass 55.6% ethanol conversion, substantially higher than the Anderson-Schulz-Flory distribution. Research shows that the porous structure and coordination between metal and alkaline sites could play key roles in C6+-OH selectivity. The catalyst recycles and reaction pathway of ethanol upgrading to higher alcohols were also discussed.

Abstract ：
以热解为首要步骤的煤炭分质转化技术可在较温和的条件下实现煤炭高效利用,其中含尘热解气净化是该技术规模化应用需要解决的关键问题之一.颗粒床过滤技术具有过滤效率高、滤料成本低等优势.为考察移动式颗粒床对粉煤热解气除尘过滤的有效性,选用小麦为颗粒床冷态试验的滤料介质,硅胶粉为试验粉尘,在自行设计的冷态试验平台上考察各操作条件对颗粒层过滤除尘效率的影响规律.结果表明:过滤效率的影响因素顺序为:表观风速＞过滤层厚度＞滤料下料速度;过滤效率随表观风速的增大而减小,随过滤层厚度的增加而增大.过滤层厚度增至200 mm以上时,过滤效率变化较小;而滤料下料速度增大,过滤效率减小.粉尘粒径达10 μm后,过滤效率基本可维持在98％.在优化的过滤条件下(过滤层厚度为300 mm,滤料下料速度为0.002 m/s,过滤时间为10 min),最佳过滤效率可达98.1％.试验结果不仅实现了对常温下移动颗粒层过滤性能的预测,也为粉煤热解含尘煤气颗粒床热态除尘装置的设计提供了依据.

Abstract ：
The dehydration reaction mechanism of 1,4-butanediol and the regulation mechanism of catalyst were studied using Gaussian 09 based on the DFT theory and transition state theory, and the thermodynamic parameters of the 1,4-butanediol reaction network were calculated. The elementary steps were determined by searching the transition state and pathway of each reaction. The strategies of both catalyst design and reaction process intensification were also clarified. Results show that the reaction network was under kinetic control within the studied temperature range due to large equilibrium constants. Kinetic studies indicated that the parallel side reaction of tetrahydrofuran formation and the tandem side reaction of 1,3-butadiene formation greatly influenced the selectivity of 3-buten-1-ol due to their low potential energy barriers. The terminal hydroxyl group and β-H can be simultaneously activated by designing an acid-base bifunctional catalyst to make 1,4-butanediol dehydrating to 3-buten-1-ol more easily. Meanwhile, the method of reducing the residence time of 3-buten-1-ol could be used to suppress the occurrence of tandem side reactions. © 2021, Editorial Board of 'Journal of Chemical Engineering of Chinese Universities'.

Abstract ：
Biomass chemical looping process (BCLP) could realize the in-situ separation of carbon dioxide with nearly zero energy consumption, making the entire conversion process carbon negative. In this paper, thermal behavior from BCLP of the main components of microalgae was investigated. Glycine (GE) and starch (ST) were selected as the main compounds of protein and carbohydrate of the main organic components of microalga. Using Fe2O3 as the oxygen carrier, thermal behavior and kinetic characteristics of main compounds under different oxygen carrier ratios and different heating rates were studied. The results showed that the chemical looping conversion behavior of GE and ST changed with the change of oxygen carrier ratio and heating rate. By studying the distribution of the main gaseous products and the low calorific value of the sample, it was found that when the mass fraction of Fe2O3 in GE reached 30 %, the low calorific value of the main gaseous products reached the maximum. Under the three heating rates of 10, 20, and 40./min, the maximum low calorific value was 8.98, 9.36 and 10.08 MJ m 3, respectively. When the mass fraction of Fe2O3 in ST reached 30 %, the low heating value of the main gaseous products at the three heating rates reached the minimum, and when Fe2O3 increased to 50 %, the low heating value suddenly rose to the maximum. The kinetic parameters of the main gaseous products showed that the activation energy required for the three gaseous products of CO, CO2 and H-2 released by GE thermal interpretation were all the smallest, which were 6.227 kJ mol(-1).2.645 kJ mol(-1).19.447 kJ mol(-1), respectively. The activation energy required for ST thermal release of CO was the smallest. Besides, ST-Fe-50 needed the least activation energy to release CH4, CO2 and H-2 through chemical looping conversion, which were 13.704 kJ mol(-1).1.824 kJ mol(-1).33.191 kJ mol-1, respectively. The research results in this paper provide references for guiding the selection of microalgae raw materials and the development of chemical looping conversion equipment.

Abstract ：
Hydrogen is a promising candidate to substitute the fossil fuels. However, the efficient hydrogen storage technologies restrict the commercial applications. Developing new cat-alysts with high activity and selectivity is important for the dehydrogenation reaction in N-ethylcarbazole/dodecahydro-N-ethylcarbazole (NECZ/12H-NECZ) hydrogen storage sys-tem. In this work, a series of Pd-M/Al2O3 (M = Co, Ni and Cu) bimetallic catalysts are synthesized successfully and show good performance in the dehydrogenation reaction of 12H-NECZ than the commercial Pd/Al2O3 catalyst. The Pd1Co1/Al2O3 catalyst (Practical Pd content = 2.4136 wt%) showed the highest catalytic performance with 95.34% H-2 release amount, TOF of 230.5 min(-1) and 85.4% selectivity of NECZ. Combined with the charac-terization analysis, it can be proposed that the dehydrogenation performance of 12H-NECZ dependent on the alloy phases, reasonable electronic structures and nanoparticle size of catalysts. The fine-tuned alloy degree and appropriate nanoparticle size of Pd1Co1/Al2O3 bring the 17.7% increase of H-2 release amount and 99.5% increase of NECZ selectivity than those of Pd/Al2O3. For the bimetallic catalysts, the enhancement of selectivity of NECZ is mainly from the increase of the kinetic constant of rate-limiting step.

Abstract ：
High performance Ni-based porous catalytically activated absorbers (PCAA) was prepared and experimentally studied for methane dry reforming reaction. Effects of critical operating parameters were discussed to disclose their influence on variation trends of outlet composition of each species. With experimental results, kinetic models of PCAAs for the complex methane dry reforming reaction were extracted by using plug flow model, nonlinear least squares fitting method as well as genetic algorithm. It was found that (1) High CO2/CH4 ratio is beneficial to increase CH4 conversion and CO/H-2 selectivities; (2) High temperature condition would increase conversions of CH4 and CO2, but decrease CO selectivity; (3) The increase of molar flow rate would decrease CH4 conversion & CO/H-2 selectivities, and increase CO2 conversion; (4) Compared to other reported models, the established kinetic models can predict the outlet molar fractions of species well, showing great potential for the design and optimization of PCAA-type solar reactor.

Abstract ：
The biomass chemical looping gasification (BCLG) of torrefied spruce-pine-fir (SPF) sawdust with Fe2O3 was studied using thermogravimetry-mass spectrometry (TG-MS). The effects of torrefaction temperature and OC ratio on the BCLG were investigated. The thermal characteristics of torrefied SPF with Fe2O3 and the distribution of gaseous products were discussed. Thermogravimetric kinetics and gas release kinetics were implemented to understand the mechanism. The results showed the volatiles release intensity of the SPF reached the maximum when the torrefaction temperature was 270 ?C. The solid?solid reaction performance between OC and biochar reached the highest as the OC fraction was 50 wt%. The thermogravimetric kinetics revealed the activation energy of the BCLG gained the minimum when the OC ratio was 50 wt%. Moreover, the increase of OC ratio and torrefaction temperature could improve the reactivity of biochar. The torrefaction affected the gaseous products distribution of the BCLG, which consequently promoted the H2/CO ratio of the syngas from 1.06 to 1.30. Meanwhile, the gas release kinetic analysis demonstrated the E(H2) made the minimum (88.66 kJ?mol- 1) when the torrefaction temperature was 270 ?C. All these indicate the torrefaction has a positive effect on the BCLG process.

Abstract ：
In the present work, a novel crown ether contained polyimide membrane was synthesized by 4, 4′- (hexafluoro - isopropylidene) diphthalic anhydride, 1, 4 - Bis (4 - aminophenoxy) benzene, and di(aminobenze)-21-Crown-7 ether. The physical property and chemical structure were studied by FTIR, 1HNMR, XRD, TGA, GPC, and tensile testing. Molecular dynamic simulations were applied to investigate the effects of crown ether content on free volume property of membranes. The permselectivity was studied employing He, H2, CO2, N2, and CH4 pure gas as feed. The effects of crown ether content, operation temperature, feed gas pressure, and aging effect on membranes were investigated. Results show that introducing crown ether into polymeric backbone can increase the chains packing density, which lead to reduce d-spacing as well as accessible fractional free volume. These permeabilities followed the order of He > H2 > CO2 > N2 > CH4, indicating a typical molecular sieving separation mechanism in membranes. The introduction of DB21C7 can improve the diffusion selectivity and solubility selectivity. For example, CO2/N2 and CO2/CH4 diffusion selectivity display impressing increase of 53% and 84% respectively by incorporation of 30 mol% DB21C7. As a consequence, the membrane with 30 mol% DB21C7 exhibit remarkable selectivity increase of about 173.5% (for He/CH4), 156.9% (for H2/CH4), 109.4% (for CO2/N2), 88.5% (for CO2/CH4) than non-crown ether contained polyimide membrane. Hence, future membrane material design for high purity gas requirement may be considered as a promising alternative membrane by introducing the crown ether moiety into the polymeric backbone. © 2021 Elsevier B.V.

Abstract ：
Torrefaction pretreatment is of great significance to the enhancements of biomass characteristics. Product distribution and kinetics analysis of spruce-pin-fir (SPF) sawdust and its torrefaction samples were studied during the fast pyrolysis process. Under anaerobic conditions, torrefied biomass was prepared at different temperatures in a slot-rectangular spouted bed reactor. Fast pyrolysis experiments were conducted in a tube furnace with online mass spectrometry. The effects of torrefaction degree and pyrolysis temperature on product distribution were discussed. The main gaseous products, ie. CO, CO2, H2, and CH4, were investigated, and kinetic data of gaseous product formation was solved based on the isoconversional method. Other volatiles were the main product during the fast pyrolysis process, and the char yield was the lowest. With the increase of torrefaction degrees, the yield of char increased from 19.80 % to 22.09 % at 800 degrees C. The pyrolysis gas yield decreased from 25.78 % to 17.18 % as the torrefaction temperature increased from 240 degrees C to 300 degrees C. The gaseous products were mainly CO and CO2. The content of CO tended to increase, and the content of CO2 decreased when the pyrolysis temperature increased. The order of activation energy was E (CO2)> E (H2) > E (CO) > E (CH4) during the fast pyrolysis of SPF. The activation energy of the CO2, CH4, and H2 increased with the increase of the torrefaction temperature. According to different evaluation indexes, the optimal setting of reaction conditions is determined.
