Catalysts in the Fluidized Bed and in the Freeboard of a Biomass Gasifier

S. Rapagnà, K. Gallucci, M. Di Marcello & P.U. Foscolo
Continuous catalytic steam gasification runs have been performed using a bubbling fluidized bed gasi.er with an internal diameter of 0.10 m, in a temperature range of 800 – 830°C. The biomass feedstock consists of crushed almond shells, with an average particle Sauter diameter of 1054 .m. Gas cleaning and conditioning is performed coupling the effect of a catalytic filter candle in the freeboard, delivered by Pall Schumacher GmbH, with a catalytic bed inventory made of...
