Abstract
Hydrocarbons are reduced in molecular weight in a conversion process wherein they are contacted with a solid catalyst comprising (i) a pillared clay and (ii) an alumina, such as gamma alumina, which has been isomorphously substituted with silicon. The treated alumina will have a silicon to fluorine mole ratio of about 1.0:1.0 to about 50.0:1.0. The process may comprise the fluidized catalytic cracking of cycle oils. For use in hydrocracking, the catalyst contains a metal hydrogenation component and possibly one or more other inorganic oxides such as silica-alumina. Other non-zeolitic materials such as silica-alumina may also be composited into the catalysts.
