Investigation on cogasification and melting behavior of ash-rich biomass solid waste and Ca-rich petrochemical sludge pyrolysis residue in CO2 atmosphere

The process of gasification coupled with melting is an effective technology that can realize the clean disposal of hazardous solid wastes. In this study, the gasification and melting characteristics of Chinese medicine residue (CMR) and pyrolysis residue of petrochemical sludge (PRPS) blends were investigated. The gasification residues obtained at different gasification temperatures and with variant blend ratios (mass ratio of CMR to PRPS) were...
