ABSTRACT:
A method of forming a sulfur-resistant catalyst is disclosed wherein a zeolite is bound with an alumina containing either an alkali or alkaline earth component. In one embodiment of this method, a solution of an alkali metal aluminate or alkaline earth metal aluminate is formed, the pH of the alkali metal aluminate solution is adjusted to a pH of from 6 to 8, and the solution is aged and mulled with a large-pore zeolite to form a mixture. This mixture is extruded to form an extrudate, which is dried, calcined, and impregnated with a Group VIII metal to form a catalyst. Finally, the catalyst is dried and calcined.
