Abstract
A method for converting hydrocarbons in a hydrocarbon stream includes contacting the hydrocarbon stream with steam and a catalyst system under steam enhanced catalytic cracking conditions to produce an effluent comprising olefins. The catalyst system includes a framework-substituted pentasil zeolite. The framework-substituted pentasil zeolite has a modified pentasil framework. The modified pentasil framework includes a pentasil aluminosilicate framework in which a portion of framework aluminum atoms of the pentasil aluminosilicate framework are substituted with Ce atoms and Fe atoms. At least a portion of the Fe atoms are monomeric.
