Abstract
A process for preparing a metallosilicate catalyst includes the steps of: forming a mixture of at least one non-alkali metal, a templating agent, and an organic base; adding a silicon additive to the mixture so as to form a metallosilicate hydrogel; aging the hydrogel to obtain a crystalline metallosilicate composition; washing and drying the crystalline composition; and calcining the crystalline composition so as to provide a metallosilicate catalyst. Two or more non-alkali metals may be selected so as to provide a multifunctional catalyst.
