The physicochemical characteristics and combustion index pointed to SMS as a promising biofuel for power generation. The high correlation coefficient of the fitting plots and similar activation energy calculated by various methods indicated that four suitable iso-conversional methods were used. The activation energy varied from 130.06 to 192.95 kJ/mol with a mean value of 171.49 kJ/ mol using Flynn-Wall-Ozawa and decreased with the increased conversion degree. The most common emissions peaked at the range of 200-400 degrees C corresponding to volatile combustion stage, except for CO2, NO2 and NO. The peak CO2 emission occurred at 439.11 degrees C mainly due to the combustion of fixed carbon.eninfo:eu-repo/semantics/closedAccessSpent Mushroom SubstrateCombustionTG-FTIRTG-MSIso-Conversional MethodsArticle10.1016/j.biortech.2018.06.106266389397299820622-s2.0-85049461249Q1WOS:000439996100048Q1
