Catalyst systems, methods to improve a catalyst system, and dimerization processes therewith are provided. Catalyst systems which comprise at least one elemental alkali metal supported on an alkali metal carbonate catalyst support, are contacted with a liquid organic solvent in order to improve the isomer ratio of the desired reaction product(s) to undesired product(s).

A dimerization process comprising contacting olefins under dimerization conditions with a catalyst system which improves the isomer ratio of the desired product(s) to undesired products and catalyst activity, wherein said catalyst system is prepared by contacting, before or after use, at least one elemental alkali metal supported on an alkali metal carbonate with a liquid organic solvent, at a temperature within a range of about 0°to about 500°C.; a pressure within the range of about 0 to about 5000 psig; under a dry, inert atmosphere; and for a time within the range of about 5 minutes to about 7 days.
