NOVELTY - Process for conversion of 1-butene to 16C butene oligomers comprises: activating a bis(cyclopentadienyl)zirconium dichloride pre-catalyst with methylaluminoxane in aromatic solvents without heteroatoms; removing the solvent to form an activated catalyst; mixing linear or branched hydrocarbon alkanes having 4-20C with the activated catalyst to form a slurry; adding dried 1-butene to slurry to the form a mixture; and stirring the mixture to allow contact of reactants at ambient temperature in a gas tight vessel until reaction is complete to form a first mixture of butene oligomers.    USE - The process is useful for conversion of 1-butene to 16C butene oligomers (claimed), which is useful as renewable biofuel for turbine engines.    ADVANTAGE - The process is simple and cost effective.
