7 Claims

1. A method for making a zeolite having MFI framework topology, comprising:

adding a source of 1,4-diazabicyclo[2.2.2]octane (DABCO), methylamine (MEA) and sodium (Na) to water to form a homogenized aqueous solution;

adding a source of aluminum to the homogenized aqueous solution to form an aluminum-containing intermediate agent;

adding a source of silicon to the aluminum-containing intermediate agent to form a synthesis gel;

subjecting the synthesis gel to conditions sufficient to crystallize a MFI zeolite; and

recovering the crystallized MFI zeolite.
