The purpose of the HighBio is to study input and output flows of the wood chips gasification process in pilot-scale gasifiers. Solid wood based biomass is used as a fuel in the gasification process. It is heated with the amount of air which is insufficient for total combustion in the gasifier, i.e. it gasifies the biomass to a mixture of carbon monoxide and hydrogen both 15-20 vol-% (synthesis gas). Pyrolysis equipment consists of the downdraft...
