Abstract

Particulate-containing gas derived from fluidized-bed biomass gasification can be efficiently purified from tars and ammonia by using a nickel monolith catalyst. Catalyst deactivation by H2S and carbon deposition can be avoided at 20 bar pressure by using temperatures over 900°C. Catalyst deactivation was not observed in a long-term test that lasted 500 h. According to a techno-economical evaluation catalytic hot gas cleaning is economically equal to ammonia removal by SCR in an 60 MWe IGCC plant.
