ABSTRACT:
An improved method for removing organic residue from ZSM-18 which can be used during zeolite synthesis or with an as-synthesized ZSM-18. When used during synthesis, a minute amount of noble metal is incorporated into the ZSM-18. Alternatively, a noble metal-containing precursor is impregnated onto as-synthesized ZSM-18. Thereafter, ZSM-18 united with the noble metal is reduced in hydrogen at 200.degree. C. for about 1 hour. Next, ZSM-18 united with the noble metal is calcined at 300.degree. C. for 10-24 hours, and subsequently at 500.degree. C. for 1-3 hours thereby producing a ZSM-18 material that is free of organic residue.
