FEASIBILITY STUDIES ON THE ENERGY VALORISATION OF AGRICULTURAL RESIDUES USING ASPEN PLUS©

摘要

The gasification of different agricultural residues (rice straw, leaves and stems from kaki fruit) on arnspouted bed reactor was studied with the aid of the commercial software Aspen Plus ©. A computational model wasrnused to study the effect of three different operational parameters (initial biomass Moisture Content – MC,rnTemperature of reaction - T and Equivalence Ratio - ER) on the final gas composition and on the overall reactorrnperformance. The reactor was assumed to be in steady state and CO, CO_2, H_2, CH_4 and H_2O were considered in thernproduced gas. The optimum operational parameters were calculated for all the studied samples. Residues from thernkaki stems were found to be those providing the highest overall efficiencies at the optimal conditions of work.
