| 3 | 高硫煤的H_2O_2-CH_3COOH溶液体系脱硫研究显示文摘采用H2O2-CH3COOH溶液体系对高硫煤进行了脱硫研究,结果表明,H2O2-CH3COOH的溶液体系可有效脱除煤中的硫铁矿硫和有机硫,实验获得的较佳脱硫条件是溶液初始的H2O2质量分数为10%,n(H2O2)∶n(CH3COOH)为10,温度为室温,反应时间60min,液固比为3∶1,搅拌速率300r/min;在此条件下,煤中硫铁矿硫的脱出率和有机硫的脱出率均可达到65%以上.对该体系的脱硫机理分析表明,H2O2的氧化性在CH3COOH的催化作用下得以加强,促使反应生成更多的羟基自由基(·OH)和过氧羟基自由基(·OOH),这些自由基具有较高的电负性或电子亲和能,能够加速脱硫反应的进行,从而实现硫铁矿硫或有机硫从煤中的脱除. | 金会心 吴复忠 | 2013 | 煤炭转化2013，36，4： | 3 |

| 6 | Optimization of a continuous ultrasound assisted oxidative desulfurization(UAOD) process of diesel using response surface methodology(RSM) considering operating cost显示文摘A continuous-flow ultrasound-assisted oxidative desulfurization(UAOD)of partially hydro-treated diesel has been investigated using hydrogen peroxide-formic acid as simple and easy to apply oxidation system.The effects of different operating parameters of oxidation stage including residence time(2–24 min),formic acid to sulfur molar ratio(10–150),and oxidant to sulfur molar ratio(5–35)on the sulfur removal have been studied using response surface methodology(RSM)based on Box–Behnken design.Considering the operating costs of the continuous-flow oxidation stage including chemical and electrical energy consumption,the appropriate values of operating parameters were selected as follows:residence time of 16 min,the formic acid to sulfur molar ratio of 54.47,and the oxidant to sulfur molar ratio of 8.24.In these conditions,the sulfur removal and the volume ratio of the hydrocarbon phase to the aqueous phase were 86.90%and 4.34,respectively.By drastic reduction in the chemical consumption in the oxidation stage,the volume ratio of the hydrocarbon phase to the aqueous phase was increased up to 10.Therefore,the formic acid to sulfur molar ratio and the oxidant to sulfur molar ratio were obtained 23.64 and 3.58,respectively,which lead to sulfur removal of 84.38%with considerable improvements on the operating cost of oxidation stage in comparison with the previous works. | Mohammad Dana Mohammad Amin Sobati Shahrokh Shahhosseini Aminreza Ansari | 2020 | Chinese Journal of Chemical Engineering2020，28，5： | 2 |

| 8 | 利用含氯聚合物和路易斯酸混合物通过吸附和烷基化反应脱除油品中的噻吩硫(英文)显示文摘For efficient removal of thiophenic sulfur(S-) compounds from oils, a novel method is proposed here, i.e. one-pot alkylation desulfurization(OADS), in which oil insoluble chlorinated polymer such as polyvinyl chloride(PVC) is used as the alkylating regent with Lewis acid as catalyst. The aromatic S-compounds are grafted to the polymer through Friedel-Crafts reaction and removed facilely along with the polymer. The OADS mechanism is identified by scanning electron microscope and analyzer with surface area and pore size of the polymer. The influence of some factors on the OADS is studied, e.g. the type and amount of chlorinated polymers and Lewis acids. It is proved that thiophene and benzothiophene can be removed efficiently from oil by PVC+AlCl3 mixture even in the presence of 25%(by mass) of benzene due to the synergetic effects of the adsorptive desulfurization of AlCl3 and the alkylation desulfurization of PVC. | 宋红艳 高家俊 陈星羽 何静 李春喜 | 2014 | Chinese Journal of Chemical Engineering2014，22，6： | 0 |
