Abstract
Torrefaction is suggested to be an effective method to improve the fuel properties of biomass and gasification of torrefied biomass should provide a higher quality product gas than that from unprocessed biomass. In this study, both raw and torrefied Miscanthus Ã giganteus (M Ã G) were gasified in an air-blown bubbling fluidized bed (BFB) gasifier using olivine as the bed material. The effects of equivalence ratio (ER) (0.18-0.32) and bed temperature (660-850 °C) on the gasification performance were investigated. The results obtained suggest the optimum gasification conditions for the torrefied M Ã G are ER 0.21 and 800 °C. The product gas from these process conditions had a higher heating value (HHV) of 6.70 MJ/m3, gas yield 2 m3/kgbiomass (H2 8.6%, CO 16.4% and CH4 4.4%) and cold gas efficiency 62.7%. The comparison between raw and torrefied M Ã G indicates that the torrefied M Ã G is more suitable BFB gasification.
