Abstract

A method for making a zeolite includes providing a reaction mixture containing mixed inorganic oxides and an organic templating agent, heating the reaction mixture, removing the templating agent at a temperature of no greater than 550° C. and under conditions such that the resulting zeolite is has an AAI of at least 1.2. The zeolite is preferably zeolite beta, TEA-mordenite or TEA-ZSM-12.
