TITLE: New Approach to the Generation of Metal-Bearing, Medium-Pore, Shape-Selective Zeolites for Fischer-Tropsch Catalysis (Aluminoferrisilicate) AUTHOR: L. E. Iton; R. B. Beal; D. T. Hodul. INST. AUTHOR: Argonne National Lab., IL. SPONSOR: Department of Energy, Washington, DC. LANGUAGE: English PUB. TYPE: Technical Report PUB. COUNTRY: United States SOURCE: Department of Energy [DE], 1983, 4p. NOTES: International zeolite conference, Reno, NV, USA, 10 Jul 1983. ABSTRACT: A new method of combining the shape-selective characteristics of zeolites with a group VIII metal component is described. It involves the following sequence of steps: (1) synthesis of an aluminoferrisilicate (AFS) zeolite, having a crystal structure analogous to zeolite ZSM-5, but which incorporates ferric ions into the structure during synthesis; (2) removal of the organic base used as a template in crystallization of the AFS zeolite; (3) reaction of the AFS zeolite with a transition metal complex anion in aqueous solution to precipitate an inclusion compound in the AFS zeolite, and (4) reduction of the inclusion compound with hydrogen at elevated temperature.
