Process for oligomerizing olefins using titanium salts or zirconium salts deposited on silicon dioxide.

摘要

Linear olefins having 10 to 24 carbon atoms can be converted into oligomers suitable for use as synthetic lubricant base stocks by contacting them at elevated temperature with a catalyst comprising titanium or zirconium oxide on a silica substrate, obtained by depositing a titanium or zirconium salt on the substrate, and then calcining at a temperature of at least 600 DEG C. In one embodiment the silica-supported titanium or zirconium oxide is sulphate-activated, and used as a blend with an acidic montmorillonite clay.
