Schweizer, A E

This patent describes a method for producing a noble metal containing zeolite catalyst for isomerization of paraffinic hydrocarbons. Contacting a zeolite material selected from the group consisting of acidic fayjasites. LZ-210 faujasites, and mordenite with a noble-metal compound selected from Pt(acetylacetonate){sub 2} and Pd(acetylacetonate){sub 2} for an effective amount of time to incorporate Pt and/or Pd into the pore surface regions of the zeolite, but not to disperse the Pt and/or Pd throughout the entire zeolite; and calcining the so treated zeolite at a temperature from about 250 {degrees} C, to about 600 {degrees} C. for an effective amount of time.
