Gasification, thermal biomass processes

Research Needsfor Thermal Gasification of Biomass, Compiled by StudsvikAB Thermal Processes, for International Energy Agency, IGT, Chicago, Mar. 1992,... 

Pyrolysis, gasification, and combustion are typical thermal conversion processes for biomass. These processes are compared and contrasted in TABLE 12-4.

Gasification. Conversion of biomass to gaseous fuels can be accompHshed by several methods only two are used by the biomass energy industry (ca 1992). One is thermal gasification in which LHV gas, ie, producer gas, is produced. The other process is anaerobic digestion, which yields an MHVgas.

RENUGAS A thermal gasification process for biomass, under development by the Institute of Gas Technology, Chicago, in the 1980s. 

Gasification coupled with water-gas shift is the most widely practiced process route for biomass to hydrogen. Thermal, steam, and partial oxidation gasification technologies are under development. Feedstocks include both dedicated crops and agricultural and forest product residues of hardwood, softwood, and herbaceous species. 

Thermochemical biomass-to-liquid (BtL) conversion, involving thermal gasification of the biomass and subsequent synthesis of biofuels by the Fischer-Tropsch process. Various aspects of the use of catalysis in this process are discussed in the several chapters. 

Most biomass gasification systems utilize air or oxygen in partial oxidation or combustion processes. These processes suffer from low thermal efficiencies and low Btu gas because of the energy required to evaporate the moisture typically inherent in the biomass and the oxidation of a portion of the feedstock to produce this energy.
