(54) METAL POLLUTION-RESISTANT CATALYST AND PREPARATION METHOD THEREFOR


(57) The present invention belongs to the technical field of catalytic cracking, and relates to a metal pollution-resistant catalyst, its preparation and application. The catalyst consists of a first alumina comprising a modified metal Mn and a second alumina. The ratio of the integral areas of the two peaks at 3670 cm-1 and 3730 cm-1 in the infrared spectroscopy of the catalyst is 1-5:1. The method for preparing the catalyst comprises a step of forming a slurry of an acid-soluble first alumina, a non-acid-soluble second alumina, water and optionally acid and a modified metal oxide. The metal pollution-resistant catalyst and the particle containing a catalytic cracking active component form a catalytic cracking catalyst, useful for catalytic cracking of hydrocarbon oil containing pollution metals. In the case of nickel pollution, catalytic cracking of hydrocarbon oil can reduce the ratio of hydrogen to methane.
