Metallic Catalysts - A Road To Clean Gas From Biomass Gasification

conference paper

Czech

Biomass as fuel is a significant source of renewable energy. In comparison with fossil fuels, however, its effective use is more complicated. This is the reason why other than conventional technologies of combustion are sought to make energy use of biomass. One of the ways of converting biomass to thermal energy or electric power is thermal gasification. The generated gas can consequently be used in combustion engines, gas turbines, or be directly burnt in the furnaces of steam boilers. Yet another interesting way of using the gas is separation and use of its individual constituents, e.g. separation of hydrogen for fuel cells. Institute of Power Engineering attached to the Faculty of Mechanical Engineering of the Brno University of Technology has for years been dealing with biomass gasification and cleaning of the generated gas. BIOFLUID 100 is a pilot plant. The benefit of research carried out using this plant is the fact that it generates a real gas that is then cleaned under real conditions and supplied to the attached technologies (in our case burning in a combustion chamber and in a combustion engine). The present article is summing up current know-how in the area of tar and gas removal using metallic catalysts in a secondary reactor. A comparison is made of the results of measurements using three kinds of metal-based catalysts involving a variety of operating conditions.
