| 摘 要： | 使用Ni-Mo催化剂,在固定床微型反应器上进行喹咻、吲哚和咔唑存在下的4,6-二甲基二苯并噻吩(4,6-DMDBT)加氢脱硫(HDS)反应.结果表明,含氮化合物对4,6-DMDBT HDS有强烈的抑制作用.这3种氮化物的抑制作用大小顺序是:喹啉、咔唑和吲哚.氮化物对于HDS 2条反应路径均有抑制作用,但是抑制的程度不同.喹啉对先加氢再脱硫(HYD)反应路径的影响比对直接脱硫(DDS)反应路径的强烈得多;吲哚存在下HYD反应为主要的HDS反应;咔唑对2条反应路径的抑制程度相似,使4,6-DMDBT HDS的HYD和DDS反应比例与不添加氮化物时相似.氮化物含量增加使4,6-DMDBT HDS中DDS反应比例增加.

| Abstract: | Inhibition effects of quinoline,indole and carbazole on the hydrodesulfurization(HDS) of 4,6-dimethyldibenzothiophene(4,6-DMDBT) over Ni-Mo catalyst were experimentally studied in a fixed-bed high-pressure micro-reactor.The three nitrogen compounds possessed very strong inhibition effects in the 4,6-DMDBT HDS,which were in the order of quinoline,carbazole and indole.They inhibited both reaction routes of the 4,6-DMDBT HDS with the different degrees.Quinoline inhibited HYD reaction route more intensely than ... |
