Preparation of hydrotreating catalyst from spent catalyst |
摘要 |
An active hydrotreating catalyst composition is prepared by a process comprising the steps of (a) grinding a spent hydrotreating catalyst containing carbonaceous deposits, (b) mixing the ground spent catalyst with an alumina-containing material (preferably alumina), (c) shaping (preferably extruding) the mixture of ground spent catalyst and alumina-containing material and (d) heating the shaped mixture so as to burn off carbonaceous deposits on the ground spent catalyst component. The thus-prepared active hydrotreating catalyst is used in a process for hydrotreating hydrocarbon containing feed streams (oils) which contain metal impurities.
