Claims3
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.
