ABSTRACT:
Crystalline palladium or platinum ferrometallosilicate compositions are prepared from a silica-containing mixture by digesting a reaction mixture comprising (a) a tetraalkylammonium compound, (b) a sodium hydroxide, (c) a titanium compound, an aluminum compound, or a manganese compound, (d) an oxide of silicon, (e) an iron ion source, (f) optionally, a chelating agent and (g) water to provide a crystalline ferrometallosilicate which is then palladium or platinum ion-exchanged. Conversion of synthesis gas to low molecular hydrocarbons with high C.sub.2 -C.sub.3 alkanes selectivity employing these new ferrometallosilicates as catalysts is also disclosed.
