ABSTRACT:
The invention relates to a process for the dry incorporation of manganese ions on the external reactive sites of Zn-ZSM-5 or Zn-ZSM-11 pentasil which comprises mixing a Zn-ZSM-5 or Zn-ZSM-11 zeolite with bentonite, impregnating the dry mixture with a minimum amount of a solution of a manganese salt thereby to form a malleable paste and extruding said paste under pressure whereby the manganese ions are affixed to the surface reactive sites of the treated zeolite and to the zeolite catalyst thus obtained.
