AbstractThere is great interest in the utilization of biomass in high efficiency power generation and in the production of high quality synthetic fuels and chemicals. Gasification, among biochemical conversion, is one way to achieve this goal. In this report the operational principle of gasification is reviewed, an analysis of different biomasses is presented and the main gasifier types are examined. The product gas composition, cleaning and utilization are examined and the commercial status of gasification is studied. There are many ways to gasify biomass, but the most common way in medium-to-large scale is to use atmospheric circulating fluidized bed gasifiers; downdraught fixed bed gasifiers are used in a smaller scale. Gasification has not yet achieved extensive usage, but it is likely to be utilized increasingly in the future as an environmentally friendly way to produce power, fuels and chemicals.
