Abstract

The invention relates to a hydrogenation catalyst carrier for coal liquefaction oil, a catalyst as well as a preparation method and application of the hydrogenation catalyst carrier and belongs to the field of hydrogenation catalysts. The carrier comprises the following components (counted by 100% of total weight of the carrier): 5-60wt% of carbon nanotube, 32-90wt% of aluminum oxide, 0-8wt% of silicon dioxide and 0-8wt% of titanium dioxide. When the hydrogenation catalyst carrier for the coal liquefaction oil is used for carrying out a hydrorefining reaction for directly liquefying low-grade oil by coal, after the reaction is continuously carried out for 48 hours, the desulfurization rate can reach 99.7%, the denitrification rate can reach 95.1%, and the deoxygenation rate can reach 99.5%; after the reaction is continuously carried out for 168 hours, the desulfurization rate can reach 98.9%, the denitrification rate can reach 94.6%, and the deoxygenation rate can reach 98.6%; the hydrogenation catalyst carrier has high catalytic activity and stability.

Description

technical field [0001] The present invention relates to a coal liquefied oil hydrogenation catalyst carrier, the catalyst and its preparation method and application, and belongs to the field of catalysts, in particular to a hydrogenation catalyst used in the coal liquefied oil hydrogenation refining process, and the carrier for preparing the catalyst , and their respective preparation methods. Background technique [0002] With the accelerated development of the industrialization process, a world-wide oil shortage will be unavoidable. my country's coal resources are the most abundant of the three major fossil energy resources. Making full use of my country's abundant coal resources and vigorously developing coal-to-oil and coal-to-oil technologies is an effective way to reduce the risk of oil shortage. At present, coal liquefied oil technology is the main method to realize coal substitution and coal oil production. Coal liquefied oil technology uses hydrogenation under hig...
