Biomass Gasification Between 800 and 1,400 degrees C in the Presence of O-2: Drop Tube Reactor Experiments and Simulation

Abstract

International audienceBeech sawdust particle conversion in a drop tube furnace was studied between 800 and 1,400 degrees C. Particular attention was paid to the influence of temperature and to the presence of oxygen on the gasification process. As temperature increases, light hydrocarbon production decreases and the CO + H-2 production (gas of interest for biofuel production) increases. Presence of oxygen in the gasification atmosphere allows consuming a high part of light hydrocarbons and enhancing carbon conversion into gas. However, high yields of CO2 and H2O were observed and the total yield of CO + H-2 was lower than in pyrolysis conditions
