Abstract
There is provided a method for preparing alpha-olefin oligomers of superior lubricating properties by contacting an alpha-olefin feed under oligomerization conditions with a catalyst comprising an activated layered silicate containing silica and oxide of Group VIB metal, e.g., Cr, between its layers. The catalyst can be activated by exposure to an oxidation gas at high temperature followed by treatment with a reducing agent, e.g., CO.
