Steam gasification of municipal solid waste for hydrogen production using Aspen Plus® simulation

Abstract Approximately 50 million ton of municipal waste is generated in Pakistan per annum and most this does not reach final deposit sites. In research, Silvia gas technology for solid (MSW) steam gasification studied to produce high energy density product gas. A detailed simulation model developed with the help Aspen Plus®. Catalyst coal bottom ash along lime (CaO) as sorbent employed tar reduction improving hydrogen (H 2 ) yield The effect operating temperature ratio feedstock on synthetic composition, heating values synthesis was studied. Coal CaO had a substantial production. Rise steam–MSW increased from 58 74.9% (vol.). maximum value production, i.e., by vol. achieved at steam–feedstock 1.9. 79.8% attained 680 °C 1.3 0.07% wt. High 13.1 MJ/Nm 3 hydrogen-rich °C. acquired results lay foundation economic feasibility study pilot plant MSW usage
