Abstract: Disclosed in certain embodiments are ZSM-5 zeolite microspheres. Disclosed in certain embodiments is a method of forming ZSM-5 zeolite microspheres including: 1) shaping a mixture into microspheres where the mixture includes a silica material and of particulates selected from at least one high-density material with an absolute bulk density of at least 0.3 g/cc, ZSM-5 zeolite crystals, and combinations thereof; 2) calcining the microspheres; and 3) reacting and subsequently heating the microspheres with at least one alkali solution to form ZSM-5 zeolite in-situ on the microspheres, where the ZSM-5 zeolite microspheres contain substantially no clay or calcined clay material.

Abstract: Disclosed in certain embodiments are ZSM-5 zeolite microspheres. The ZSM-5 zeolite microspheres may contain substantially no clay or calcined clay material. The ZSM-5 zeolite microspheres may have a ZSM-5 zeolite content of at least 70 wt. %. Disclosed in certain embodiments is a method of forming ZSM-5 zeolite microspheres including treating microspheres with at least one alkali solution.
