Zeolites (ZSM-5, boralites, offretite, HY, mordenite, and omega) were bonded with 20 wt% sepiolite into composite catalysts to oligomerize propylene in a fixed-bed, automated pilot unit operating at 30-50 atm under isothermal conditions. Product distributions indicate that oligomer size and structure correlates well with the zeolite pore diameter. In addition to C/sub 6/-C/sub 12/ and higher oligomers, aromatics and branched saturates are formed, indicating the presence of cracking, hydrogen and methyl transfer, isomerization, and dehydrocyclization reactions. Offretite (and HY) minimize C/sub 7/ and C/sub 8/ formation, while the boralite used has shown better oligomerization activity and product yields than either ZSM-5 or the other zeolites tested.
