Hydroprocessing catalyst for petroleum hydrocarbon and preparing method thereof

The present invention discloses a petroleum hydrocarbon hydrogenation treatment (hydro-denitrogenation, hydro-desulfurization, hydro-demetalization and hydro-saturation, etc) catalyst and its preparation method. Said invented preparation method includes the following steps: using alumina containing pseudo-thin diaspore and molybdenum or tungsten as raw material, fully mixing them, kneading and extruding to make it into the form of cloveleaf pattern, drying and high-temp. roasting to obtain the alumina carrier containing molybdenum or tungsten, then impregnating said carrier with aqueous solution of nickel and/or cobalt compound, drying and roasting at high-temp. as to obtain the invented hydrogenated treatment catalyst. 本发明公开了一种石油烃类加氢处理(加氢脱氮、加氢脱硫、加氢脱金属和加氢饱和等)催化剂及其制备方法。以含有拟薄水氧化铝和一种第VIB族金属如钼或钨为原料，经充分混合、捏合并挤成三叶草条状，经过干燥、高温焙烧等步骤，制成含钼或钨的氧化铝载体。然后以含有第VIII族金属如镍和/或钴化合物的水溶液浸渍该载体，经过干燥和高温焙烧，制得加氢处理催化剂。
