低温煤焦油加氢反应规律及产品分布
Hydrogenation and product distribution of low temperature coal tar
摘要
Abstract
The hydrogenation of low temperature coal tar distillate(below 360℃) was carried out over a commercial MoNi/γ-Al2O3 catalyst in a 500 mL autoclave to produce clean liquid fuel. The feedstock and products were determined by means of GC-MS to investigate the effects of temperature, pressure and reaction time on the product composition. The results showed that alkylnaphthalenes and phenols were the two most abundant compounds in the feedstock,with the contents of 23.66%and 30.12% respectively. In the hydrogenation process,high temperature was not beneficial to the conversion of alkyl-naphthalene to alkyl-tetralin,high pressure could promote the conversion;the alkyl-naphthalene hydrogenation mainly occurred in the first ring and the major products were phenyl olefins and alkyl-tetralin;high pressure and high temperature were conducive to the hydrogenation of phenols and the major products were cycloalkanes and alkyl-benzene. In summary,the feedstock was clearly upgraded after the hydrotreating.关键词
