Abstract

The invention discloses a carrier material and a preparation method thereof, a catalyst and application, the carrier material is hollow carbon-containing alumina, and the preparation method comprises the following steps: (1) preparing a carrier mother sphere; (2) preparing a carrier precursor; and (3) preparing the carrier. And introducing the active metal component into the prepared carrier material, and further drying and roasting to obtain the hydrogenation catalyst. The carrier material provided by the invention is carbon-containing aluminum oxide with a hollow structure, and the catalyst prepared by taking the carbon-containing aluminum oxide as the carrier can greatly shorten the diffusion path of reactants in the catalytic material, improve the pore channel utilization rate of the catalytic material, reduce the use amount of active metal of the catalyst and improve the utilization rate of the active metal; the action between the carrier and the active metal is proper, and the obtained catalyst has high impurity removal activity and is especially suitable for the field of hydrogenation catalysis of heavy oil and residual oil.

Description

technical field [0001] The invention belongs to the technical field of catalytic materials, in particular to a catalytic material and its preparation method and application. Background technique [0002] With the rapid development of my country's economy and society, environmental pollution has become more and more serious, people's awareness of environmental protection has gradually increased, and the country's environmental protection regulations have become increasingly strict, which puts forward higher requirements for the quality of fuel oil. This drives refiners to develop cleaner production processes and produce higher quality clean fuels. At the same time, with the gradual decrease in the supply of light crude oil and the gradual increase in the proportion of heavy high-sulfur crude oil, the processing of low-quality crude oil has become an urgent problem for refineries and is the key to the economic benefits of the entire plant. The fluidized bed hydrogenation tech...
