Abstract
There are disclosed catalysts and process for oligomerizing C.sub.3 -C.sub.12 olefins in the liquid phase at 50.degree. C.-150.degree. 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.
Claims13
A process for oligomerizing C.sub.3 -C.sub.12 olefins which comprises contacting a C.sub.3 -C.sub.12 olefin or mixtures thereof in the liquid phase at a temperature of about 50.degree. C. to about 150.degree. 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.sub.2 ;Al.sub.2 O.sub.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.
