Abstract
A process for producing alcohols from carbonaceous materials such as biomass. The carbonaceous material, such as biomass, is gasified to produce synthesis gas. The synthesis gas then is subjected to a plurality of reactions to produce alcohols having at least four carbon atoms such as butanol and isobutanol.
Claims9
A process for producing at least one alcohol, said at least one alcohol having at least four carbon atoms, from a carbonaceous material, comprising:
- (a) gasifying said carbonaceous material to provide a crude synthesis gas;
- (b) purifying the crude synthesis gas to provide a purified synthesis gas;
- (c) reacting at least a portion of said carbon monoxide with at least a portion of said hydrogen from said purified synthesis gas to provide methanol;
- (d) reacting said methanol under conditions to provide a product comprising dimethyl ether;
- (e) reacting said dimethyl ether under conditions to provide at least one olefin;
- (f) reacting said at least one olefin with synthesis gas in a hydroformylation reactor to provide a product comprising at least one alcohol having at least four carbon atoms;
- and
- (g) recovering said at least one alcohol having at least four carbon atoms from said product of step (f).
