Billaud J., Valin S., Ratel G., Thiery S., Salvador S., 2014, Biomass Gasification Between 800 and 1,400 °C in the Presence of O2: Drop Tube Reactor Experiments and Simulation, Chemical Engineering Transactions, 37, 163-168.
Beech sawdust particle conversion in a drop tube furnace was studied between 800 and 1,400 °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 + H2 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 + H2 was lower than in pyrolysis conditions.
