摘      要：The catalytic effects of four industrial wastes,namely,the soap residue(SR),brine sludge(BS),calcium carbide residue(CCR),and white lime mud(WLM),on coal thermal ignition were *** acidity of palmitate anion associated with Na+in SR was lower than that of chloride anion combined with Na+in BS,which resulted in an improved the combustion of *** acidity of OH-anion combined with Ca2+in CCR was lower than that of CO32-anion combined with Ca2+in WLM,resulting in CCR exhibiting a better catalytic effect on coal *** alkaline metal Na had lower initial ionisation energy than the alkaline earth metal ***,the Na-rich SR exhibited higher catalytic activity on coal ignition than Ca-rich *** ignition temperature of coal with 0.5%SR decreased from 544 to 503°C.
