Abstract

The invention relates to a heavy distillate oil selective hydrogenation catalyst and application thereof, and mainly solves the technical problems of low catalyst activity, high aromatic hydrocarbon loss and the like in the prior art. The heavy distillate oil selective hydrogenation catalyst comprises a carrier and an active component, wherein the active component is selected from at least one ofa nickel element, a rare earth metal element and an IB metal element. According to the technical scheme, the technical problemsare well solved, and the heavy distillate oil selective hydrogenation catalyst can be used in heavy distillate oil selective hydrogenation production.

Description

technical field [0001] The invention relates to a catalyst for selective hydrogenation of heavy distillate oil and its application, more specifically to a catalyst for selective hydrogenation of naphthalene components in heavy distillate oil and a method for selective hydrogenation of heavy distillate oil. [0002] Background of the invention [0003] In recent years, with the large-scale construction and capacity expansion of oil refining units and ethylene units, my country's oil refining capacity and ethylene production capacity have increased rapidly, and due to the trend of diversification and heavy-duty raw materials, the output of by-product heavy oil has also continued to increase , which is quite considerable. How to rationally use this part of heavy resources to develop downstream products and turn waste into treasure has become an urgent problem for many enterprises to solve. [0004] Ethylene tar and C 10 + The output exceeds 5 million tons per year, and the res...
