Abstract

The invention relates to a hydrogenation thermal decomposition catalyst and a method for preparation of fuel oil from the same. The catalyst is a desulfurizer waste agent, the active component of the desulfurizer is one or more of NiO, MoO, CoO and WO3 and has a content of 10-50wt%. The method for preparation of fuel oil from a coal tar hydrogenation thermal decomposition catalyst comprises the step of: in the presence of the catalyst, and under the conditions of a hydrogen pressure of 10-20MPa, a reaction temperature of 400-470DEG C, and a hydrogen-oil flow ratio of 250-700 (l / kg), subjecting the coal tar to hydrogenation thermal decomposition reaction. The coal tar hydrogenation thermal decomposition catalyst is a waste catalyst of a petroleum hydrodesulfurization project, and can be obtained without preparation, thus saving the cost of raw materials.

Description

[0001] The invention belongs to the field of coal chemical industry, and in particular relates to a hydrothermal decomposition catalyst and a method for preparing fuel oil using the same. Background technique [0002] With the rapid development of the economy and the increasing energy consumption, petroleum resources as traditional liquid fuels are decreasing day by day. Therefore, in view of the specific national conditions of "lack of oil, less gas, and rich coal" in my country, the development of clean coal produced by coal Oil products are a good way to ease the tension of oil resources. [0003] Research results in recent years have shown that using coal tar as raw material to produce clean crude oil by means of hydrothermal decomposition has obvious economic and social benefits. Hydrothermolysis refers to the hydrogenation, cracking and isomerization reactions of heavy coal-based oils under the condition of relatively high pressure and temperature under the action of hydr...
