A catalyst comprising MCM-36 and a hydrogenation/dehydrogenation component.
A method for preparing a catalyst comprising MCM-36 and a hydrogenation/dehydrogenation component, said method comprising the steps of:
- (i) preparing a reaction mixture capable of forming a layered material upon crystallization, said reaction mixture containing sufficient amounts of alkali or alkaline earth metal cations, a source of silica containing at least about 30 wt % solid silica, an oxide of aluminum, water and hexamethyleneimine;
- (ii) maintaining said reaction mixture under sufficient crystallization conditions until crystals of layered material are formed;
- (iii) swelling said layered material of step (ii) by contacting said layered material with a suitable swelling agent;
- (iv) contacting the swollen material of step (iii) with a suitable pillaring agent under conditions sufficient to generate MCM-36;
- and
- (v) combining MCM-36 with a hydrogenation/dehydrogenation component.
