1. A process of producing a catalyst, the process comprising:

forming mesoporous beta zeolite particles, the forming step comprising:

converting a crystalline beta zeolite to a non-crystalline material with reduced silica content relative to the crystalline beta zeolite; and

crystalizing the non-crystalline material to produce mesoporous beta zeolite particles;

impregnating the mesoporous beta zeolite particles with a metal and phosphorus to produce a metal and phosphorus impregnated zeolite; and

incorporating the metal and phosphorus impregnated zeolite with clay and alumina to produce the catalyst.
