Synthetic crystalline ferroborosilicate compositions, the preparation thereof and their use in the conversion of synthesis gas to low molecular weight hydrocarbons
Crystalline ferroborosilicate compositions are prepared from a silica containing mixture by digesting a reaction mixture comprising a tetraalkylammonium compound, a sodium hydroxide, a boron compound, an oxide of silicon, an iron ion source, an optional chelating agent and water to provide the crystalline ferroborosilicate which is then palladium ion-exchanged. This composition may be used alone or physically mixed with a methanol catalyst. Conversion of synthesis gas, dimethylether, ethylene and methanol to low molecular hydrocarbons employing these new ferroborosilicates as catalysts is also disclosed.
