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.
Claims8
A catalyst composition consisting of a zeolite containing an amount of nickel effective for oligomerization of C.sub.3 -C.sub.12 olefin, which catalyst is prepared by a process consisting of (1) adding nickel in the form of nickel chloride or nickel nitrate to the zeolite 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 faujasite and zeolites zeolite isostructural with mazzite and (2) vacuum calcining said nickel-containing zeolite composition at a temperature of about 375.degree. C. to 475.degree. C.
