Abstract:
Processes and multiple-stage catalyst systems are disclosed for producing propylene from butene by at least partially metathesizing butene in a metathesizing reaction zone having a metathesis catalyst to form a metathesis reaction product and at least partially cracking the metathesis reaction product in a cracking reaction zone having a cracking catalyst to form a cracking reaction product that includes propylene. The metathesis catalyst may be a mesoporous silica-alumina catalyst support impregnated with metal oxide having a mesoporous silica-alumina catalyst support comprising from 5 weight percent to 50 weight percent alumina. The cracking catalyst may be a MFI structured silica-containing catalyst. The cracking reaction zone may be downstream of the metathesis reaction zone.

Claim (Index 4):
The process of  claim 2  where the feed stream comprises:\n from 20 wt. % to 60 wt. % of cis- or trans-2-butene, or both; \n from 10 wt. % to 20 wt. % of 1-butene; and \n from 5 wt. % to 20 wt. % n-butane.
