Catalytic reforming process using noble metal alkaline zeolites
This patent describes improvement in a process wherein a gasoline boiling range hydrocarbonaceous feedstock is catalytically reformed in the presence of hydrogen in a reforming process unit comprised of serially connected reactors wherein each of the reactors contains a supported noble metal-containing catalyst. The improvement comprises the noble-metal catalyst of at least one reactor being selected from the group consisting of alkaline faujasite zeolite, L zeolite and zeolites isostructural thereto, which catalysts are prepared by a: contacting an alkaline faujasite zeolite, L zeolite, or zeolite isostructural thereto, with a noble metal composition selected from Pt(acetylacetonate){sub 2} or Pd(acetylacetonate){sub 2} for an effective amount of time to form a substantially homogeneous mixture and to incorporate the platinum and/or palladium into the near surface regions of the zeolite, but not to disperse the platinum and/or palladium 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.
