Abstract:
Embodiments of processes for producing propylene utilize a dual catalyst system comprising a mesoporous silica catalyst impregnated with metal oxide and a mordenite framework inverted (MFI) structured silica catalyst downstream of the mesoporous silica catalyst, where the mesoporous silica catalyst includes a pore size distribution of at least 2.5 nm to 40 nm and a total pore volume of at least 0.600 cm 3 /g, and the MFI structured silica catalyst has a total acidity of 0.001 mmol/g to 0.1 mmol/g. The propylene is produced from the butene stream via metathesis by contacting the mesoporous silica catalyst and subsequent cracking by contacting the MFI structured silica catalyst.

Claim (Index 1):
A process for production of propylene comprising:\n contacting a stream comprising butene with a metathesis catalyst in a metathesis catalyst zone, passing the stream comprising butene directly from the metathesis catalyst zone to a cracking catalyst zone comprising a cracking catalyst, and contacting the stream comprising butene with the cracking catalyst in the cracking catalyst zone, where the stream comprising butene contacts the metathesis catalyst before contacting the cracking catalyst.
