A method for producing a zeolite catalyst includes mixing a zeolite material with a filler material comprising transition phase and alpha alumina, a porosity enhancing agent, and water to produce a paste; mulling the paste; extruding the paste to produce a shaped extrudate; and drying and calcining the shaped extrudate to produce a zeolite catalyst, wherein the zeolite catalyst has a total porosity greater than about 0.60 ml/gm and greater than 15% of a total pore volume of pores in the range from about 550 Å to about 31,000 Å. |
