Hydrogen-rich syngas production via catalytic gasification of
The biomass sample obtained by mixing wheat straw and wet sludge with a moisture content of 80% was used as the raw material for hydrogen-rich syngas production. The proximate and ultimate analyses of dry sludge and wheat straw are listed in Table 1 and presented on an air-dried basis.
A Novel Process of Biomass Gasification for Hydrogen-Rich Gas
A new process of biomass gasification with a catalytic solid heat carrier is proposed that is called the ECCMB (external circulating concurrent moving bed) gasification system. The system is composed of a moving-bed gasification zone and a combustion zone. A circulation loop of bed material, which acts as catalyst and heat carrier, is achieved between these two zones. The char circulated with
