Adaptation of the Simplex Gasification Process to the Co-Conversion of Municipal Solid Waste and Sewage Sludge

摘要

This study examined the combining of coal with biomass and sewage sludge in varying ratios to form simplex briquettes to be fed into gasifiers. Under study was the question of whether the use of biomass, sewage sludge and municipal solid wastes permit the use of Eastern-caking coals in commercial medium-Btu gasifiers. The results of the study found that many of the 225 experimental briquette formulations meet the required structural integrity; prevent the clumping and fusing that have hindered effective gasification of this type of coal; and meet storage criteria. The briquettes developed in this project, if commercially available, could convert an urban disposal problem into an energy resource while also permitting the use of less expensive and more readily available Eastern coal. Additional larger-scale testing will be needed before the briquettes can be marketed.
