摘要

The growing attention on carbon dioxide emissions by coal-fired power plants has led to an increase in coal blending with biomass. Coal blending with biomass is practiced for economic considerations keeping coal quality in mind. Thus, the thermal parameters involved during pyrolysis and combustion of coal, miscanthus, and tobacco stems as measured in thermogravimetric (TG) analysis experiments can be applied. There is a need to determine the relationships that exist between the measured values of TG thermal parameters in individual coal and biomass and those in the blends. The TG thermal parameters are mass loss, T _i, T _f, T _p, t _f, and the maximum mass loss rate (DTG_(max)). In this study, a series of lignite coal and biomass blends with and without mineral content were investigated. Thermal parameters for the blends were measured to examine the additive and nonadditive nature of results obtained under both pyrolysis and combustion conditions using TG analysis. The nonadditive nature of coal blended samples may be due to the mixed catalysts effect (synergism). Thus, the mixed catalysts play an important nonadditive role in several reaction pathways.
