Abstract

Embodiments of a metathesis process for producing propylene comprise providing a metathesis catalyst comprising an amorphous mesoporous silica foam impregnated with metal oxides, where the metathesis catalyst has a pore size distribution of at least 3 nm to 40 nm and a total pore volume of at least 0.700 cm3/g. The process further involves producing a product stream comprising propylene by contacting a feed stream comprising butene with the metathesis catalyst.
