Problems solved by technology

However, the above-mentioned patents mostly use alumina as the carrier. Although it has been modified, the interaction with active metals is still strong, which hinders the further improvement of the catalyst activity. At the same time, the heavy oil hydrogenation catalyst using alumina as the carrier, the catalyst becomes Hazardous waste, waste catalyst treatment and reuse steps are cumbersome and costly, which is not conducive to the wide application of catalysts

Abstract

The invention discloses a catalytic material with hydrogenation performance and a preparation method and application thereof. The catalytic material takes petroleum coke-based activated carbon as a carrier, and has large specific surface area, pore volume and pore diameter. The preparation method comprises the following steps of: (1) well mixing petroleum coke, a pore-enlarging agent and an auxiliary agent, and then contacting the mixture with water vapor for treatment; (2) mixing a sample obtained in the step (1) with an acid solution, and further washing and drying the sample to obtain a carrier; (3) preparing an aqueous solution containing a hydrogenation metal component and P from a compound containing the hydrogenation metal component, a phosphorus-containing compound and water; and (4) mixing the aqueous solution obtained in the step (3) with the carrier obtained in the step (2), standing, drying and roasting to obtain the catalytic material. The catalytic material has higher hydrogenation activity, and the catalyst has high metal capacity and better stability.

Description

technical field [0001] The invention belongs to the technical field of petrochemical industry, and relates to a catalytic material and a preparation method thereof, in particular to a catalytic material with hydrogenation performance and a preparation method thereof. Background technique [0002] At present, judging from the trend of primary energy consumption in my country and the world, oil will continue to be the mainstream energy in the world for a long time. With the continuous development of my country's economy, the demand for oil is increasing year by year. Although my country's oil production is gradually increasing, it still cannot meet the actual demand, resulting in an increase in my country's net oil imports year by year, and the dependence on foreign countries has exceeded 70%. For companies like Sinopec Such a large oil importer has a higher degree of dependence on foreign countries. Residue is the most impurity-laden, heaviest component of petroleum and is di...
