A kind of catalyst carrier and its supporting method and use

Abstract

A catalyst carrier and its loading method and application, the active component of the catalyst is one or more combinations of metal compounds of Group VIII and VIB, and the carrier is a powdery substance with adsorption capacity, wherein the carrier The bulk density is 0.8-3.0g / cm3, the specific surface area is 100-1000m2 / g, the average pore diameter is 6-300nm, the pore volume is 0.2-1.5cm3 / g, and the carrier accounts for 12wt%-95wt% of the total mass of the catalyst . The density and hardness of the carrier with the parameters of the present invention are relatively small, which can greatly enhance the dispersion of the catalyst, thereby enabling the catalyst to maximize its catalytic activity, low wear on equipment, pumps, valves and pipelines, good delivery status, and low cost .

Description

technical field

[0001] The invention relates to a catalyst carrier and its loading method and application, belonging to the fields of petrochemical and coal chemical industries. Background technique

[0002] my country is a country rich in coal and poor in oil. In dealing with the contradiction between oil supply and demand and implementing energy conservation and emission reduction policies, making full use of coal and heavy oil resources is an important choice to ensure energy security. Slurry bed hydrogenation technology is an important technology for converting coal and heavy oil into light oil and chemicals. This technology is suitable for heavy oil hydrogenation, direct coal liquefaction and oil-coal mixing processes.

[0003] Based on the above reasons, the slurry bed hydrogenation technology, especially the slurry bed hydrogenation catalyst, has become a research hotspot in recent years. Since the slurry bed hydrogenation catalyst is a disposable catalyst, considerin...
