Abstract

The gasification of different agricultural residues (rice straw, leaves and stems from kaki fruit) on a spouted bed reactor was studied with the aid of the commercial software Aspen Plus ©. A computational model was used to study the effect of three different operational parameters (initial biomass Moisture Content ¿ MC, Temperature of reaction - T and Equivalence Ratio - ER) on the final gas composition and on the overall reactor performance. The reactor was assumed to be in steady state and CO, CO2, H2, CH4 and H2O were considered in the produced gas. The optimum operational parameters were calculated for all the studied samples. Residues from the kaki stems were found to be those providing the highest overall efficiencies at the optimal conditions of work.
