Gas Cleaning in Electricity Production via Gasification of Biomass: Conclusions of the Workshop

Abstract

Although the conversion technologies in biomass gasification for the production of fuel gas have progressed significantly during the last twenty years the downstream cleaning of the gas had attracted little interest initially and is lacking in technological progress. It is now generally accepted that all types of gasifiers do produce tar and dust at various yields and that these undesirable by-products must be effectively removed before the gas can be used in internal combustion engines or gas turbines for power production or other applications. This is also reflected by the research community since several programmes have been initiated during the last five years in this field.
