Hydrotreating catalyst and preparing method thereof

The invention discloses a hydrocarbon hydrogenation processing catalyzer and preparing method, using pseudo-thin water containing alumina, silicon-containing compound and a VIB-family metal like Mo or Wu as raw materials, mixing fully, kneading and extruding into bars, drying, making high-temperature baking, etc, to make Mo or Wu-containing alumina carrier, then drying and making high-temperature baking to obtain the catalyzer. It can maintain higher Mo or Wu dispersivity even on high-Mo or Wu content condition. Besides, it also has higher specific surface area and larger aperture capacity. The hydrogenation reaction activity and anti-nitrogen performance are both better. 本发明公开了一种烃类加氢处理催化剂及其制备方法。以含有拟薄水氧化铝、含硅化合物和一种第VIB族金属如钼或钨为原料，经充分混合、捏合并挤条成型，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VIIIB族金属如镍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。采用本发明方法制备的催化剂，即使在高钼或高钨含量的情况下，同样可以保证钼或钨有较高的分散度。同时，还会有较高的比表面积和较大的孔容。其加氢反应活性及催化剂抗氮性能均优于用普通方法制得的催化剂。
