Title:

ADSORBENT, LIQUID PHASE HYDROGENATION CATALYST COMPOSITION, CATALYST BED AND USE THEREOF

Document Type and Number:

WIPO Patent Application WO/2022/089637

Kind Code:

A1

Abstract:

The present invention relates to an adsorbent, a liquid phase hydrogenation catalyst composition containing the adsorbent, a catalyst bed containing the liquid phase hydrogenation catalyst composition, and the use thereof in adsorption technology or oil product liquid phase hydrogenation technology. The adsorbent comprises a porous material and a hydrogenation active metal loaded on the porous material. The adsorbent has an average pore size of 2-15 nm and a specific surface area of 200-500 m2/g. In addition, based on the total weight of the adsorbent, the mass content, calculated by means of metal oxide, of the hydrogenation active metal, is 2.5 wt% or less. The adsorbent has a high hydrogen sulfide adsorption efficiency and a long duration time, such that the protection period of a hydrodesulfurization catalyst is effectively prolonged.
