N2 - Metallurgical industry accounts for 20.40% of the total energy consumption in the industry of China. Energy saving from furnace slag of the steel industry is essential for the clean and green development of China. Thus, in this paper, the thermal effect and kinetic analysis of the biomass mixed with furnace slag at different mass ratios (10 wt%, 30 wt.% and 50 wt.%) was investigated via TGA under different heating rate from ambient temperature to 900oC. Cellulose was selected as the primary organic compound in biomass, and iso-conversional method was applied for calculating activation energy. The maximum decomposition rate and temperature of maximum decomposition rate get higher as the heating rate increases. Furnace slag shows positive synergistic effects under 30% mass ratio with 6% higher volatile yield than that from theory calculation. The average activation energy values of CE, Slag-CE-10, Slag-CE-30, Slag-CE-50 were 187.54 kJ·mol-1, 260.81 kJ·mol-1, 132.79 kJ·mol-1 and 159.45
