Abstract
The invention relates to a process for producing ketones or hydrocarbon base oil from fatty acids preferably derived from a biological origin or other renewable source. The process is directed at making an aliphatic ketone or a mixture of aliphatic ketones having 14 to 52 carbon atoms, comprising a ketonization reaction of a fatty acid in a vapor phase with a decarboxylation-coupling catalyst to provide ketones, which can be deoxygenated to give saturated hydrocarbons, unsaturated hydrocarbons, and mixtures thereof. Base oils and transportation fuels may be produced from the process herein.
Claims13
A process for making an aliphatic ketone or a mixture of aliphatic ketones having about 14 to 52 carbon atoms, comprising:
- reaction of a fatty acid in a vapor phase with a decarboxylation-coupling catalyst in a decarboxylation-coupling zone, wherein a decarboxylation-coupling zone temperature is between about 20° C. to 100° C. above the condensation point of the fatty acid at the partial pressure of the fatty acid in the decarboxylation-coupling zone.
A process for making an aliphatic ketone or a mixture of aliphatic ketones having about 14 to 52 carbon atoms, comprising:
- reaction of a fatty acid in a vapor phase with a decarboxylation-coupling catalyst in a decarboxylation-coupling zone, wherein a partial pressure of the fatty acid is between 1% and 90% of the partial pressure at the condensation point at a given decarboxylation-coupling zone temperature.
