Abstract
An operation is described which involves the catalytic cracking of high boiling hydrocarbons in the presence of hydrogen and carbon-hydrogen contributing fragments in the presence of particularly crystalline zeolite conversion catalysts promoting the chemical reactions of cracking, hydrogen redistribution, olefin cyclization and chemical reactions providing mobile hydrogen in one of several different forms and suitable for completing desired hydrogen transfer reactions. The chemical reactions desired are particularly promoted by a mixture of large and smaller pore crystalline zeolites in the presence of hydrogen contributing materials such as methanol or mixed with one or more reactants which will form methanol under suitable reaction conditions.
