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.
