1. A method for producing a catalyst composition, the method comprising:
forming a precursor solution comprising a silicon-containing material, an aluminum-containing material, and a quaternary amine;
hydrothermally treating the precursor solution at a first temperature to form an intermediate mixture;
hydrothermally treating the intermediate mixture at a second temperature to form beta zeolite, wherein the first temperature is less than the second temperature by at least 200° C.;
forming an extrudable mixture comprising the beta zeolite, alumina, a metal precursor, and a binder;
extruding the extrudable mixture to form extrudates; and
calcining the extrudates to form the catalyst composition.
