Abstract
A process for the use in the oligomerization of olefins is presented. The process produces a gasoline boiling range product having a high research octane number and almost no aromatics content. The process utilizes a solid catalyst comprising a zeolite that is treated with a phosphorous containing reagent to generate a catalyst having phosphorous content between 0.5 and 15 wt %.
Claims33
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, wherein the catalyst comprises a molecular sieve and a binder, wherein the catalyst has been treated with a phosphorous containing reagent, thereby forming a treated catalyst having a micropore volume less than 50%, and a crystallinity greater than 50% of the untreated catalyst.
A process for the oligomerization of an olefin containing feed, comprising:
- contacting the olefin containing feed, having olefins in the range from C2 to C5, with a solid catalyst at oligomerization reaction conditions, in an oligomerization reactor, thereby forming an intermediate olefin stream containing an olefin product having a molecular weight greater than 72 g/mol, wherein the catalyst comprises a molecular sieve and a Al2O3 binder, wherein the catalyst has been treated with a phosphorous containing reagent, thereby forming a treated catalyst having a micropore volume less than 50% of the untreated catalyst, and a crystallinity greater than 50% of the untreated catalyst.
