Abstract
The present disclosure generally relates to the catalytic conversion of alcohols into hydrocarbon ketones suitable for use as fuels. More specifically, the present disclosure relates to the catalytic conversion of a mixture of isopropanol-butanol-ethanol (IBE) or acetone-butanol-ethanol (ABE), into ketones suitable for use as fuels. The ABE or IBE mixtures may be obtained from the fermentation of biomass or sugars.
Claims16
A method of producing a mixture of hydrocarbon ketones, comprising contacting acetone and at least two or more primary alcohols with catalyst and optionally base to produce a mixture of hydrocarbon ketones, wherein at least a portion of the mixture of hydrocarbon ketones is produced from double alkylation of the acetone, and
- wherein the catalyst comprises Pd, Cu, and hydrotalcite (HT).
A method of producing a mixture of hydrocarbon ketones, comprising contacting acetone and at least two or more primary alcohols with catalyst and optionally base to produce a mixture of hydrocarbon ketones, wherein at least a portion of the mixture of hydrocarbon ketones is produces from doubly alkylation of the acetone, and
- wherein the catalyst comprises Pd—Cu/HT, Pd—Cu/HT-C, Pd—Cu/HT/C, Pd—Cu/NiHT, or PdCu/ZnHT, or any combinations thereof.
A method of producing a mixture of hydrocarbon ketones, comprising:
- a) contacting biomass or sugars with a fermentation host to produce a fermentation product mixture, wherein the fermentation product mixture comprises acetone, butanol and ethanol;
- b) isolating at least a portion of the acetone, butanol and ethanol from the fermentation product mixture;
- and
- c) contacting the isolated acetone, butanol and ethanol with metal catalyst and optionally base to produce a mixture of hydrocarbon ketones, wherein at least 20% of the mixture of hydrocarbon ketones are C7+ hydrocarbon ketones and wherein at least a portion of the mixture of hydrocarbon ketones is produced from doubly alkylation of the acetone, and
- wherein the catalyst comprises Pd, Cu, and hydrotalcite (HT).
