However, the mechanism is always proposed based on physicochemical structure and reactivity of char mixture. In this work, char mixture after co-pyrolysis of anthracite and biomass was separated based on different shape and size, and then structure and reactivity of the coal char were analyzed to reveal mechanism of coal-biomass interaction. Anthracite char samples with different corn straw (CS) blending ratios were prepared by pyrolysis in a fixed bed reactor at 600 and 900℃. The AAEM concentration and microcrystalline structures of coal char were examined by inductively coupled plasma-optical emission spectrometry (ICP-OES) system and X-ray diffraction (XRD). The gasification reactivity of char sample after separation was analyzed by TGA under CO2<\/sub>. The results show that concentration of active K and Mg in coal char samples gradually increased and more disordered carbon structure formed as the CS proportion in the blending increased from 0 to 80%. The coal char in the blending captured more AAEM species by volatile-char interactions instead of escaping with volatile from biomass during co-pyrolysis process. Meanwhile, higher pyrolysis temperature led to volatilization and inactivation of K and Na, and also decrease in graphitization degree. Moreover, both addition of CS and low pyrolysis temperature could promote gasification reactivity of coal char sample. Furthermore, a satisfactory linear correlation (R<\/i>2<\/sup>=0.9009) between alkali index AI<\/i> and R<\/i>0.5<\/sub> of the char samples was established. This indicated that AAEMs performed the dominate effect to enhance gasification reactivity of coal char during co-gasification of coal and biomass.","articleNo":"","authorCnList":["李晓明"," 张红"," 刘梦杰"," 智丽飞"," 白进"," 白宗庆"," 李文"],"authorEnList":["LI Xiao-ming"," ZHANG Hong"," LIU Meng-jie"," ZHI Li-fei"," BAI Jin"," BAI Zong-qing"," LI Wen"],"authorList":["LI Xiao-ming"," ZHANG Hong"," LIU Meng-jie"," ZHI Li-fei"," BAI Jin"," BAI Zong-qing"," LI Wen"],"authors":"LI Xiao-ming, ZHANG Hong, LIU Meng-jie, ZHI Li-fei, BAI Jin, BAI Zong-qing, LI Wen","authorsCn":"李晓明, 张红, 刘梦杰, 智丽飞, 白进, 白宗庆, 李文","authorsEn":"LI Xiao-ming, ZHANG Hong, LIU Meng-jie, ZHI Li-fei, BAI Jin, BAI Zong-qing, LI Wen","categoryName":"Articles","categoryNameCn":"论文","categoryNameEn":"Articles","citation":"LI Xiao-ming, ZHANG Hong, LIU Meng-jie, ZHI Li-fei, BAI Jin, BAI Zong-qing, LI Wen.

It is found that combustion temperature has a significant effect on the release of K. At 600-750℃, with an increase in temperature, water-soluble K and NH4<\/sub>Ac-soluble K are released to the gas phase, which makes the release ratio of K fast; while at 750-850℃, water-soluble K and NH4<\/sub>Ac-soluble K begin to convert into other forms of K and are fixed in the ash sample, which makes the release rate of K slow; when the temperature is higher than 850℃, as the temperature increases, the decomposition of HCl-soluble K causes the release rate of K increase again. Through XRD analysis, it is found that the water-soluble K in ash mainly exists in the form of KCl. The production of K2<\/sub>SO4<\/sub> is affected by both the K content in the raw material and the S/Cl ratio, the higher the content of K in raw materials, and the greater the ratio of S/Cl, the more it will promote the formation of K2<\/sub>SO4<\/sub>.

However, the SiO2<\/sub>/Al2<\/sub>O3<\/sub> ratios for all the modified ZSM-5 samples increased due to the dealumination. Furthermore, Fe was detected in Fenton-ZSM-5 while no Fe was observed for FeSO4<\/sub>-ZSM-5 catalyst. The BET surface areas and total pore volumes of three modified catalysts significantly increased compared with the original ZSM-5 sample. Among them, the BET surface area of the Fenton-ZSM-5 increased by 17.86%.The increase of mesopores was probably caused by the removal of the residual organic template in the catalysts due to the generation of·OH radicals by Fenton's reagent and H2<\/sub>O2<\/sub>. The Fenton-ZSM-5 catalyst formed new acid sites of Brønsted (B) and Lewis (L) with little change in the total calculated amount, which significantly changed the B/L ratio. Compared with the parent ZSM-5, the Fenton-ZSM-5 catalyst exhibited the best activity and stability for propene oligomerization reaction. The initial propene conversion and diesel selectivity were as high as 98.3% and 92.4%, respectively, and kept at >80% and >82% for about 24 h, respectively.","articleNo":"","authorCnList":["訾仲岳"," 李冰爽"," 葛元征"," 刘广波"," 李建青"," 吴晋沪"],"authorEnList":["ZI Zhong-yue"," LI Bing-shuang"," GE Yuan-zheng"," LIU Guang-bo"," LI Jian-qing"," WU Jin-hu"],"authorList":["訾仲岳"," 李冰爽"," 葛元征"," 刘广波"," 李建青"," 吴晋沪"],"authors":"訾仲岳, 李冰爽, 葛元征, 刘广波, 李建青, 吴晋沪","authorsCn":"訾仲岳, 李冰爽, 葛元征, 刘广波, 李建青, 吴晋沪","authorsEn":"ZI Zhong-yue, LI Bing-shuang, GE Yuan-zheng, LIU Guang-bo, LI Jian-qing, WU Jin-hu","categoryName":"论文","categoryNameCn":"论文","categoryNameEn":"Articles","citation":"訾仲岳, 李冰爽, 葛元征, 刘广波, 李建青, 吴晋沪. 芬顿试剂改性ZSM-5分子筛上丙烯齐聚反应研究. 燃料化学学报, 2020, 48(8): 986-992.","citationCn":"訾仲岳, 李冰爽, 葛元征, 刘广波, 李建青, 吴晋沪. 芬顿试剂改性ZSM-5分子筛上丙烯齐聚反应研究. 燃料化学学报, 2020, 48(8): 986-992.","citationEn":"訾仲岳, 李冰爽, 葛元征, 刘广波, 李建青, 吴晋沪.

With the increase of LHSV, H2<\/sub>/oil, reaction pressure and temperature, the dealkylation rate, the total selectivity of aromatics, and the selectivity of light aromatics first rose and then dropped. The conversion of 4-ethylphenol was obviously influenced by the reaction temperature. Cr2<\/sub>O3<\/sub>/Al2<\/sub>O3<\/sub> was modified with different concentrations of phosphoric acid. As the increase of the amount of phosphoric acid, the general amount of weak and medium acids on the catalyst increased, and the strength of acid was first enhanced and then weakened. The amount of weak acid increased significantly under a high value of the amount of phosphoric acid. Compared with the unmodified catalyst, the conversion of 4-ethylphenol on the catalysts modified by 8% phosphoric acid is higher than 99.5%, while the dealkylation rate of 4-ethylphenol increased by 9.4%, reaching to 74.4%, and the selectivity to light aromatics (benzene and toluene) increased by 4.0%, reaching to 57.0%. Conversion of 4-ethylphenol to light aromatics was achieved in high selectivity. Furthermore, the total selectivity of aromatics was as high as 80.4%, which meant that most of the aromatic rings was not broken.
