## Abstract

A process for producing acrylic acid 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 acrylic acid.

## Claims

### Claim 1

A process for producing acrylic acid 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 the carbon monoxide from said purified synthesis gas with hydrogen from said purified synthesis gas to provide methanol;
(d) reacting said methanol under conditions to provide a product comprising at least one olefin, where said at least one olefin comprises propylene; and
(e) subjecting said propylene to one or more reaction steps to produce acrylic acid.

### Claim 2 (depends on 1)

The process of claim 1 wherein said at least one olefin further comprises ethylene, and said ethylene is reacted to produce ethanol.

### Claim 3 (depends on 1)

The process of claim 1 wherein said carbonaceous material is biomass.
