Waste Gasification For Power Generation: Assessment Of Industrial And Non-Industrial Alkaline Residues As Sorbents For Acid Gas Removal

The search of sustainable and affordable materials for the cleaning of acid gas in biomass gasification is one of the many challenges for the development of commercial gasification-based waste-to-energy plants. This study presents the potential sorbents identified in the literature. An analysis of these alkaline residues is done inspired by the Draft Specifications for the Application of UNFC to Anthropogenic Resources (UNECE/2017/SED/78). The classification is based on three categories: technical performance, societal-economic impact and environmental impact. The most interesting residue for its use in the acid gas removal of waste gasification power generation is the red mud followed by seafood shells.
