Abstract
A process for producing alcohols having three carbon atoms 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 such as n-propanol and isopropanol.
Claims7
A process for producing at least one alcohol, said at least one alcohol having three 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 ethylene;
- (f) reacting said ethylene with synthesis gas in a hydroformylation reactor to provide a product comprising at least one alcohol having three carbon atoms;
- and
- (g) recovering said at least one alcohol having three carbon atoms from said product of step (f).
