Abstract

This chapter discusses the gasification of solid fuel at a high temperature and pressure and cleans the gas to the level required by the gas turbine. The most important cleaning requirements are related to particulate matter and certain corrosive components. The high temperature, high pressure filter dust of air-blown solid fuel gasification is significantly developed pore structure with a relatively high surface area. Pore structure is dependent on the gasification feedstock and process conditions, such as gasification temperature and residence time. The dust removes the particulate by forming the filtration cake on the filter surface. The porous dust behaves as an adsorption material and adsorbs the organic impurities of high boiling point from the gasification gas.
