Abstract
Processes for producing synthesis gas from biomass in which char particles, which are formed during the production of synthesis gas from biomass, are employed as catalysts. The char particles may be used as catalysts in a gasifier or in a thermal reformer, whereby gaseous components, formed as a result of the gasification of the biomass, such as methane, light alkyl and aromatic compounds, and phenolics, as well as tar, may be reformed and/or converted into synthesis gas.
Claims8
A method of producing synthesis gas from biomass, comprising:
- (a) gasifying a biomass-rich material in a gasifier under conditions which produce a product comprising a gas comprising a crude synthesis gas and char particles;
- (b) separating said char particles from said gas;
- and
- (c) passing said char particles to said gasifier.
A method of producing synthesis gas from biomass, comprising:
- (a) gasifying a biomass-rich material in a gasifier under conditions which produce a product comprising a gas comprising a crude synthesis gas and char particles;
- (b) separating said char particles from said gas;
- (c) passing said gas to a steam reforming and/or water gas shift and/or dry reforming zone;
- (d) pelletizing said char particles;
- and
- (e) passing said pelletized char particles to said steam reforming and/or water gas shift and/or dry reforming zone, wherein said gas is subjected to reforming in said steam reforming and/or water gas shift and/or dry reforming zone in the presence of said pelletized char particles.
A method of producing synthesis gas from biomass, comprising:
- (a) gasifying a biomass-rich material in a gasifier under conditions which produce a product comprising a gas comprising a crude synthesis gas and char particles;
- (b) separating said char particles from said gas;
- and
- (c) treating said char particles with steam or with oxygen and steam or with air or with oxygen enriched air or with carbon dioxide, or any mixtures thereof;
