摘要

Gasification of Cynara cardunculus L. was performed in a bubbling fluidized bed (BFB) using air as gasifying agent and, magnesite and olivine as different bed materials. Temperature was varied during the experiments (700-800 degrees C) with fixed biomass feeding and air flow rate. The effect of using the magnesite and olivine on gas and tar composition, carbon and biomass conversion, and cold gas efficiency was investigated. The product gas showed high hydrogen content (13-16% v/v) for both magnesite and olivine in the studied temperature range. Higher heating value and gas yield were improved with increasing the temperature from 700 to 800 degrees C. Biomass and carbon conversion were greater than 75%, obtaining values higher than 90% for both 700 and 800 degrees C in magnesite and for 800 degrees C in olivine. Small differences in total tar were observed between materials, although tar composition was very different. BTEX were higher for olivine and similar PAHs was obtained for both magnesite and olivine. A higher catalytic activity at 800 degrees C was observed for magnesite. Gasification performance was better with magnesite at 700 degrees C while olivine showed better properties at 800 degrees C.
