Abstract
An alpha-olefin is oligomerized in the presence of a three-component catalyst comprising a particulate solid adsorbent having boron trifluoride and water adsorbed on the solid adsorbent. For example, 1-decene is oligomerized to a product predominating in the trimer and tetramer using silica as the solid adsorbent.
Claims13
The process for oligomerizing an alpha-olefin having from three to twelve carbon atoms and mixtures thereof with a heterogeneous catalyst which comprises contacting said alpha-olefin in a reactor at a temperature between about -50.degree. and about 150.degree. C. with a three-component solid catalyst comprising a solid adsorbent in particulate form having a boron trifluoride and water adsorbed thereon.
The process for oligomerizing 1-decene to a product predominant in the trimer of 1-decene which comprises contacting a stream of 1-decene containing from about 5 to about 130 ppm. water and a stream of boron trifluoride with a catalyst comprising particulate silica at a temperature of between about -10.degree. and about 50.degree. C. under a partial pressure of boron trifluoride between about 10 and about 500 psig. (about 0.17 and about 3.55 MPa).
A method of regenerating a deactivated solid catalyst comprising boron trifluoride adsorbed on a solid adsorbent which has been deactivated in the oligomerization of an alpha-olefin, the step which comprises contacting said deactivated solid catalyst with a stream comprising a liquid alpha-olefin containing dissolved water.
