ABSTRACT OF THE DISCLOSURE "IMPROVEMENTS IN CATALYST PRODUCTION" Catalysts of the ZSM-5 synthetic zeolite type can be prepared by heating a mixture of a precursor for an alumina hydrate, a pre- cursor for silica hydrogel, an alkali metal hydroxide and water to- gether with an organic templating agent selected from the group of carboxymethylcellulose, the condensation product of an alkanolamine and a fatty acid and cellulose hydroxyethyl ether and thereafter heating the reaction product under autogenous conditions. Unlike prior proposals ZSM-5 which is uncontaminated by other zeolites, is prepared in high yield.
