Comparative Process Study of Biomass Gasification for Power and Chemical Production

E. Biagini, M. Simone, C. Nicolella & L. Tognotti
Based on the preliminary tests of the CRIBE downdraft gasifier, that successfully operated with wood chips, wood pellets and sunflower residues, a model of the reactor and the process is developed to predict the most important process performances (syngas composition, tar content, biomass conversion, maximum temperature achieved). A commercial software (Aspen Plus®) is used to develop a detailed model and relate operating conditions, biomass characteristics and reactor parameters. Although many literature works modeled all gasifiers...
