Katalysator und Wasserstoffbehandlungsverfahren

摘要

Catalyst comprising a porous inorganic refractory oxide wherein the catalyst has: (a) a total pore volume in the range of from 0.2 to 0.5 ml/g, (b) a macroporosity of at least 0.1 ml/g, (c) a microporosity of at least 0.05 ml/g, and (d) a surface area of at least 5 m2/g. Process for reducing the amount of solid contaminants and the amount or dissolved metallic contaminants, wherein a hydrocarbon oil containing such contaminants is contacted with hydrogen under hydrotreating conditions in the presence of the above catalyst.
