Patent ID: 8178740

Claim:
A process for the oligomerization of an olefin containing feed, comprising: contacting the olefin containing feed at oligomerization conditions, having olefins in the range from C2 to C12, with a solid catalyst at reaction conditions thereby forming a polygasoline product comprising highly branched alkenes, wherein the catalyst comprises a zeolite and a binder, wherein the zeolite has a structure selected from the group consisting of MFI, MEL, ITH, IMF, TUN, FER, BEA, FAU, BPH, MEI, MSE, MWW, UZM-8, MOR, OFF, MTW, TON, MTT, AFO, ATO, and AEL, and mixtures thereof, wherein the catalyst has been treated with a phosphorous containing reagent selected from the group consisting of phosphate compounds, phosphite compounds, phosphorus oxytrichloride, and mixtures thereof, thereby forming a treated catalyst having a micropore volume less than 50%, and a crystallinity greater than 50% of the untreated catalyst.
