A catalyst composition for the cracking of heavy oil, which has high cracking activity for heavy components in the heavy oil and features reduced deposition of coke. The catalyst composition is comprised of a zeolite, a mixed metal oxide, clay and a metal oxide, and the total acidity of a portion of said catalyst, said portion being composed of said catalyst components other than said zeolite, is from 0.02 to 0.08 mmol/g.

Process for making a catalyst for cracking heavy oil

A catalyst composition for the cracking of heavy oil, which has high cracking activity for heavy components in the heavy oil and features reduced deposition of coke. The catalyst composition is comprised of a zeolite, a mixed metal oxide, clay and a metal oxide, and the total acidity of a portion of the catalyst; the portion being composed of the catalyst components other than the zeolite, is from 0.02 to 0.08 mmol/g.

Catalyst for cracking heavy oil

An additive catalyst for the cracking of heavy oil, characterized in that the additive catalyst includes: (i) a mixed metal oxide composed of an acidic metal oxide and a basic metal oxide, in which the proportion of the basic metal oxide is from 5 to 50 mole %, (ii) clay, and (iii) silica.
