摘要

摘要: 在固定床加氢微反装置上,考察了邻甲酚对煤焦油组分喹啉加氢脱氮(HDN)反应、二苯并噻吩(DBT)加氢脱硫(HDS)反应以及1-甲基萘加氢饱和(HDA)反应的影响。结果表明,邻甲酚的加入对喹啉的HDN反应、DBT的HDS反应、1-甲基萘的HDA反应有着较强的抑制作用,且邻甲酚的含量越多,这种抑制作用越明显,这是由于邻甲酚与喹啉、DBT、1-甲基萘在活性位点上的竞争吸附造成的。邻甲酚的加入对产物的选择性影响较弱,反应前后产物的选择性变化很小。由于空间位阻效应,1-甲基萘的加氢优先发生在不带侧链的芳环上。

Abstract: The influence of o-cresol on HDN of quinoline, HDS of DBT and HDA of 1-methylnaphthalene were investigated over a commercial catalyst in a fixed bed micro-reactor. The results suggest that o-cresol could strongly inhibit the HDN reaction of quinoline, HDS of DBT and HDA of 1-methylnaphthalene. The inhibition effect increases with the increasing content of o-cresol, which is resulted from the competitive adsorption between o-cresol and quinoline, DBT, and 1-methylnaphthalene. The presence of o-cresol has little effect on product selectivity. The hydrogenation is favored for aromatic ring without side chain, which is accounted for the steric effect.
