Abstract:
1. A method for removing C 9+ aromatic compounds from the linear alpha-olefins product of the oligomerization of ethylene in the presence of an organic solvent and an oligomerization catalyst, comprising separating the linear alpha-olefins product into molecular weight fractions including at least a C 10+ alpha-olefins fraction which comprises C 10+ alpha-olefins and C 9+ aromatic compounds and then subjecting the C 10+ alpha-olefins fraction to an alkylation reaction wherein C 10+ alpha-olefins and the C 9+ aromatic compounds in the C 10+ alpha-olefins fractions are reacted in the presence of a Friedel-Crafts alkylation catalyst to produce C 19+ aromatic compounds.
