Gasification of biomass to SNG and medium BTU gas by either bioconversion or thermochemical processes is discussed. A preliminary evaluation of IGT's BIOTHERMGAS process has shown that combining biochemical and thermochemical gasification results in an economic process with a higher conversion efficiency and a greater choice of feedstocks that can be processed than either biological or thermochemical processes used separately. The biogasification component can receive high moisture feeds, can convert major portions of feed at low temperature and pressure, and can be used for methanation of synthesis gas. The thermochemical gasifier converts refractory organic residues from the anaerobic digesters and provides gases that can be used for heating, mixing, and stimulating methanogenesis in the biological component. Research planned for further demonstration of the technical and economic feasibility of the process will include further evaluation of the process at the laboratory scale, a more detailed systems and economic study, and process design and scale-up.
