Title:
METHOD FOR CONVERTING BIOMASS INTO SYNTHESIS GAS USING A PRESSURIZED MULTI-STAGE PROGRESSIVELY EXPANDING FLUIDIZED BED GASIFIER FOLLOWED BY AN OXYBLOWN AUTOTHERMAL REFORMER TO REDUCE METHANE AND TARS
Document Type and Number:
WIPO Patent Application WO/2010/022096
Kind Code:
A3
Abstract:
The invention provides systems and methods for converting biomass into syngas using a pressurized multi-stage progressively expanding fluidized bed gasifier to eliminate or reduce the formation of methane, volatiles such as BTX, and tars. The gasifier may include a reactive stage that may receive a biomass feed through a feed line and oxygen through an oxygen feed line. The gasifier may also include a fluidized bed section that may be configured to receive the reaction products from the first stage, mix them and perform fluidized bed activity. A gasifier may also have a disengagement section that may be configured to separate fluidized media and particulate matter from syngas product. A gasification system may also include oxyblown catalytic autothermal reactor and a cryogenic air separation unit.
