Syngas production through biomass/CO2 gasification using granulated blast furnace slag as heat carrier
The emerging technology of biomass/CO2 gasification to recover waste heat from granulated blast furnace (BF) slag for solving the energy crisis and relieving the greenhouse effect was proposed. The gasification performances of biomass/CO2 in granulated BF slag under different reaction temperatures and mole ratios of CO2 to fixed carbon in the biomass (CO2/C) were investigated, and the effects of granulated BF slag on the biomass/CO2 gasification reaction were illuminated. The results showed that with higher gas content, gas yield, and lower heating value (LHV) were obtained with higher reaction temperature. When CO2/C was up to 1, the maximum concentrations of CO and H2 were obtained, and the LHV was near maximum value. Granulated BF slag could promote biomass/CO2 gasification reactions to some degree and also could act as a catalyst in the reaction. Under the optimum conditions, a reaction temperature reaching 1000 °C, CO2/C of 1 and using granulated BF slag as a heat carrier, the maximum syngas concentrations of CO and H2 were 43.1% and 33.7%, and the gas yield and LHV were 1.453 m3/kg and 16.089 MJ/kg, respectively.
