ABSTRACT:
A composition and a process for catalyzing ethylene oligomerization employing the composition as catalyst are disclosed. The composition comprises a nickel compound, a phosphine compound, and a phosphated alumina where the phosphated alumina is both a component of and a support for the composition. The ethylene oligomerization process comprises (1) combining a nickel compound and a phosphine compound in a solvent to form a mixture; (2) combining the mixture with a phosphated alumina under ethylene pressure to form a catalyst system; (3) contacting ethylene with the catalyst system under oligomerization conditions to produce higher olefins having more than 2 carbon atoms.
