Abstract
Abstract There are disclosed catalysts and process for oligomerizing C3-C12 olefins in the liquid phase at 50 DEG C-150 DEG C in the presence of a nickel containing zeolite catalyst, the zeolite being a Cs or Ba exchanged CSZ-1, high silica ultra-stable faujasite and zeolites isostructural with mazzite.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
121 words
A process for oligomerizing C 3 -C 12 olefins which comprises contacting a C 3 -C 12 olefin or mixtures thereof in the liquid phase at a temperature of about 50° C. to about 150° C. with a calcined nickel-containing zeolite catalyst, the nickel being added in an amount of from about 0.2% to about 20% by weight either by cation exchange or by impregnation, the zeolite being selected from the group consisting of cesium or barium exchanged CSZ-1, high silica ultra-stable faujasites having a SiO 2 ;Al 2 O 3 ratio of at least about 4.09 and zeolites isostructural with mazzite, the catalyst exhibiting a turnover number of at least 25 moles of olefin per mole of nickel per hour.
Claim 2
Dependent Claim
121 words
