Abstract

The invention provides a coal-oil hydroprocessing coal-loaded catalyst, a preparation method and application thereof. The catalyst contains an active ingredient, a co-active ingredient and a carrier, wherein the active ingredient is iron and molybdenum in a molar mass ratio of 35:1-1:1, the iron is water-soluble iron salt, and molybdenum is water-soluble molybdenum salt; the co-active ingredient is sulfide having a molar mass ratio to the active ingredient of 1:3-1:5; and the carrier is pulverized coal. The preparation method comprises the following steps: (1) weighing iron salt and molybdenum salt, adding into water to prepare a salt mixed solution; (2) adding sulfide and a proper amount of alcohol into the salt mixed solution, uniformly stirring and mixing, heating while stirring to a proper temperature, and adding pulverized coal to react; and (3) cooling to room temperature after the reaction in the step (2) is completed, and drying. The catalyst has the advantages of high hydrogenation activity, good coke inhibiting effect, high coal conversion rate and the like, is simple in preparation, and is suitable for large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of oil-coal hydrogenation co-refinery catalysts, and in particular relates to a coal-oil hydrogenation co-refinery supported catalyst, a preparation method and an application thereof. Background technique [0002] On the one hand, with the heavy and inferior crude oil and the increasing demand for light products year by year, the processing of heavy oil, especially low-quality residual oil with high carbon residue, high sulfur and nitrogen, and high metal has become the development trend of refineries. On the other hand, my country is rich in coal resources, and the proven reserves are second only to the United States and Russia. The direct combustion of a large amount of coal has brought an increasingly heavy burden to environmental protection. In order to solve the problem of oil and coal utilization, coal-oil suspension bed hydrogenation co-refining technology was born. It can make use of the synergisti...
