Abstract

See full text

A process for making SSZ-39 zeolite employing at least one organic structure-directing agent (OSDA), in which a substantial quantity of the at least one OSDA, which otherwise would be required to form a zeolite such as SSZ-39, is replaced by at least one quaternary ammonium or phosphonium compound (PFA) or a mixture of two or more thereof that is not itself an OSDA for making SSZ-39. A composition including at least one oxide of silicon; faujasite; at least one organic structure directing agent (OSDA) for making SSZ-39 zeolite; at least one PFA that is not an OSDA for making SSZ-39 zeolite; an alkali metal hydroxide; and water.
