Optimization of air-gasification technology of the lignocellulosic biomass Cistus monspeliensis (CM) and the pure woody pseudo components (cellulose, hemicellulose and lignin) was realized by amplifying experiments in a semi-batch reactor. For each single sample, the effect of the both temperature (750-900°C) and air fraction in nitrogen (0%-48%) on the gasification performance including gas product yield and gas chemical composition were discussed in depth. The results indicated that the increase of gasification temperature and air fraction was found to increase the production of gas during the gasification process of biomass, cellulose, hemicelluloses and lignin. CO, CO2, H2 and CH4 are main components of the gas phase. 4% of air was found to be the optimal fraction in the gasification of CM and this value was applied in the gasification of cellulose, hemicellulose and lignin. The gas composition with the highest CO production was obtained from cellulose (48%-51%) at 0% air, while lignin produced more hydrogen and less CH4 than others.
