Abstract
Olefinic hydrocarbons containing from 3 to about 6 carbon atoms in which the olefinic linkage is in a terminal position are oligomerized by treatment with a heterogeneous oligomerization catalyst which is prepared by treating an activated metal oxide of Group IIIA of the Periodic Table with a titanium tetrafluoride compound at an elevated temperature.
Claims8
A catalyst preparation method which comprises heating a metal oxide which possesses surface hydroxyl groups with hydrogen or nitrogen at a temperature of from about 350.degree. to about 550.degree. C., impregnating the thus heated metal oxide with a solution of titanium tetrafluoride, cold rolling the impregnated oxide for a time period of from about 0.5 to about 4 hours, then steam drying at about 100.degree. C. and further drying at about 200.degree.-600.degree. C. in an inert atmosphere.
