Abstract
The invention provides catalysts for the catalytic cracking of heavy oil, comprising an iron-containing crystalline aluminosilicate zeolite. This crystalline aluminosilicate zeolite is obtained by treating a raw crystalline aluminosilicate zeolite material with an acidic solution containing iron ions, or alternatively, by applying a steam treatment and, thereafter, treating with an acidic solution containing iron ions. The use of the catalyst provides a gasoline fraction having a high octane value and an intermediate fraction from heavy oil in high yield.
