Title:
METHOD AND DEVICE FOR GASIFYING BIOMASS
Document Type and Number:
WIPO Patent Application WO/2011/134961
Kind Code:
A3
Abstract:
In order to gasify biomass, the raw material (12) is supplied to a gasification reactor (32) via a supply device (10), a pyrolysis unit (14), an oxidation unit (16) and a reduction unit (18) being arranged in direct contact with one another in said reactor. The raw material (12) is degassed in the pyrolysis unit (14) and is converted to the pyrolysis products. The pyrolysis products are burnt in the oxidation unit (16) while a gasification agent (44) is supplied. The oxidation products are converted to product gas (22) in the reduction unit (18) and the product gas (22) is removed from the gasification reactor (32) via an outlet (20). At least part of the product gas (22) is used to heat the raw material (12) in the pyrolysis unit (14), the raw material (12) being completely degassed in the pyrolysis unit (14) and being completely separated to give a solid phase consisting of carbon and a gaseous phase consisting of the pyrolysis gases.
