硫含量对煤直接液化性能的影响 晋香兰1,田新娟1,杨平平2,李小彦1,李育辉1 (1.煤炭科学研究总院西安研究院,陕西,西安,710054;2.西北有色金属研究院,陕西,西安,710016) 摘要:利用实验室高压反应釜,研究了榆林横山樊河长焰煤中硫含量对煤直接加氢液化反应的影响.结果表明:随着煤中硫含量的增加,油产率和总转化率均先增加再减小;当硫的质量分数为6.65%和4.37%时,油产率和总转化率分别达到最大值49.79%和86.38%;水产率无明显变化规律;除1号煤样,气产率和氢耗量随硫含量的增加而增加;煤中硫,矿物质及体系中氢共同作用催化了煤的加氢液化反应. 关键词:硫含量; 液化性能; 催化剂; sulfur content; liquefaction reactivity; catalyst; [全文内容正在添加中] ......

with positive correlation to the ferric ion concentration. The activation energy obtained from Arrhenius empirical formula is 51.39 kJ/mol. The EDS and XPS analyses suggest that the oxidation of sulfur within pyrite is through a series of intermediate stages, and eventually is oxidized to sulphate accompanied with the formation of element sulfur. This indicates a thiosulfate oxidation pathway......
