Title:
INTEGRATED, HIGH-EFFICIENCY PROCESSES FOR BIOMASS CONVERSION TO SYNTHESIS GAS
Document Type and Number:
WIPO Patent Application WO/2010/124077
Kind Code:
A3
Abstract:
The present invention provides several variations for converting biomass, and other carbon-containing feedstocks, into syngas. Some variations include pyrolyzing or torrefying biomass in a devolatilization unit to form a gas stream and char, and gasifying the char. Other variations include introducing biomass into a fluid-bed gasifϊer to generate a solid stream and a gas stream, followed by a partial-oxidation or reforming reactor to generate additional syngas from either, or both, of the solid or gas stream from the fluid-bed gasifϊer. Hot syngas is preferably subjected to heat recovery. The syngas produced by the disclosed methods may be used in any desired manner, such as conversion to liquid fuels (e.g., ethanol).
