煤液化油的催化加氢脱杂原子反应受多种因素影响,其中反应条件的影响较大。反应条件不但影响反应的脱硫率、脱氮率、产物的H/C 原子比、气体产率等,还与催化剂积炭率有密切关系。在煤液化油加氢反应中,催化剂表面积炭是导致催化剂失活的主要因素。对催化剂积炭量研究的很多,但很少报道积炭量随反应条件的变化规律。选择合适条件进行煤液化油催化加氢,是煤液化工程技术上的一个 Catalytic hydrodesulfurization of coal liquefaction oil is affected by many factors, among which reaction conditions have a great influence. The reaction conditions not only affect the reaction desulfurization rate, denitrification rate, product H / C atomic ratio, gas yield, but also closely related to the rate of catalyst coke deposition. In coal liquefaction oil hydrogenation reaction, the catalyst surface carbon deposition is the main factor leading to catalyst deactivation. There are many studies on the amount of coke deposited on the catalyst, but few reports on the variation of carbon deposition with the reaction conditions. Select the appropriate conditions for catalytic liquefaction of liquefied petroleum gas is a coal liquefaction engineering technology
