Abstract
Catalyst supports, catalyst systems, methods for the preparation thereof, and dimerization process therewith are provided. Catalyst systems comprise at least one elemental alkali metal and at least one paraffinic material deposited on an alkali metal carbonate catalyst support. Optionally, the catalyst system further comprises at least one promoter and at least one carbonaceous compound.
Claims20
A composition comprising:
- (a) at least one elemental alkali metal supported on an alkali metal carbonate support;
- (b) wherein component (a) is then treated with at least one paraffinic material at a temperature sufficient to maintain both said paraffinic material and said elemental alkali metal in a liquid, or molten, state but not sufficient to destroy or decompose said component (a) or said paraffinic material thereby forming a coated composition.
A process to prepare a treated catalyst composition comprising:
- (a) forming a particulate catalyst support comprising an alkali metal carbonate;
- (b) contacting said particulate catalyst support with an elemental alkali metal to form a catalyst;
- and
- (c) treating said catalyst with at least one paraffinic material at a temperature sufficient to maintain both said paraffinic material and said elemental alkali metal in a liquid, or molten, state but not sufficient to destroy or decompose said catalyst or said paraffinic material to form a coated catalyst.

A process to prepare a treated catalyst composition comprising:
- (a) forming a particulate catalyst support comprising potassium carbonate;
- (b) contacting said particulate catalyst support with liquid elemental potassium to form a catalyst;
- (c) thereafter, treating at a temperature of about 80.degree. C., said catalyst with decane to form a coated catalyst;
- and
- (d) cooling said coated catalyst.
