Abstract

The invention provides a carrier for a residual oil hydrogenation catalyst and the catalyst based on the carrier. The carrier is prepared by the following steps of (1) respectively weighing kaolin original soil and a pore-enlarging agent according to the mass ratio of 1:4 to 1:8, uniformly mixing, and performing pore-enlarging processing for 1 to 8 hours in a gas atmosphere of one or two of nitrogen, oxygen, air and carbon dioxide in a temperature condition of 500 to 800 DEG C; (2) pickling a pore-enlarged product from the step (1), water-washing, and then drying at 100 to 150 DEG C, so as to obtain the carrier of the residual oil hydrogenation catalyst. The carrier prepared by adopting the preparation method has a large pore diameter, pores with the radius of 50 to 80nm accounts for more than 70% of the total number of the pores, the specific surface area can reach 120 to 220m<2> / g, and when hydrogenation reaction is performed on heavy oil or residual oil, the carrier is favorable for rapid diffusion and mass transfer of asphaltene.

Description

technical field [0001] The invention relates to a carrier, a residue oil hydrogenation catalyst based on the carrier and a preparation method thereof, belonging to the field of residue oil hydrogenation catalysis. Background technique [0002] With the development of heavy and inferior crude oil in the world, and the increasing scarcity of crude oil resources, it is particularly important to effectively process heavy oil and crude oil residues, among which hydrogenation technology is to process heavy and residues to make them lighter. One of the most effective programs. However, due to the heavy and residual oil containing a large amount of impurities such as metals, sulfur, and nitrogen, as well as a large amount of residual carbon that is easy to coke, these impurities will pollute the corresponding catalyst in the subsequent processing, and even lead to the poisoning of the corresponding catalyst. , which will have a great impact on the stability of heavy and residual oi...
