SUPPORTED CATALYST FOR SUSPENDED BED HYDROCRACKING OF INFERIOR RESIDUE OIL, AND PREPARATION METHOD THEREFOR

摘要

Disclosed is the preparation of a supported catalyst for the suspended bed hydrocracking of an inferior residue oil, which belongs to the field of catalyst preparation. The catalyst is composed of a metal active component and a carrier material, wherein the metal active component is one or more of the elements Mo, W, Co or Ni, in an amount of 1-10 wt% of the total amount of the catalyst, and the carrier material is modified rectorite, where a modifying method is one of a roasting process or hydrothermal treatment process, and the modification temperature thereof is 400-1000ºC. The preparation method for the catalyst is an incipient-wetness impregnation method. In the present invention a high-performance catalyst for suspended bed hydrocracking of an inferior residue oil is prepared by controlling the usage amount of a hydrogenation active phase and a structural property of the carrier material, and has the characteristics of having a simple preparation process, a low price and being non-toxic. The catalyst, when applied to a suspended bed hydrocracking reaction, has the advantages of high selectivity with respect to naphtha and intermediate distillate oils, low gas and coke production rates, etc.
