COMPOSITION, METHOD OF REDUCING SELF-HEATING ABILITY OF PRELIMINARILY SULFATED AND SULFIDIZED CATALYST, HYDROTREATMENT METHOD, TRANSPORTATION METHOD, AND UNLOADING METHOD Russian patent published in 1999 - IPC

FIELD: cracking catalysts. SUBSTANCE: self-heating characteristics of self-inflammable catalyst are reduced by impregnating at least a part of catalyst with one oxygen-containing hydrocarbon derivative containing at least 16 carbon atoms. When sulfur- containing catalysts are treated, self-heating characteristics are suppressed with no essential risk of reduced sulfur retention or loss of activity. In addition, treated hydrocracking catalysts exhibit elevated yield of product. EFFECT: reduced self-heating characteristics. 35 cl, 15 tbl
