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.

A metathesis process for producing propylene comprising:
- 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;
- and
- producing a product stream comprising propylene by contacting a feed stream comprising butene with the metathesis catalyst, where the metathesis catalyst has a total acidity from 0.125mmol/g to 0.500 mmol/g, and a surface area of 400 to 500 m2/g.
