With CO₂ gas and steam, gassification rate of anthracite coal containing various of ashes were measured.
The reaction of C + CO₂ and C + H₂O in this work is followed the rate of chemical reaction, and was expressed as two stage reaction like M. A. Mayer's work.
C + CO₂ Reaction
kc₂ = （(2.24×10¹⁰）/ T^-1/2)․e^-(55.790/RT) (900∼1,070 ℃)
kc₂ = （(5.89×10⁶/ T^-1/2）․e^-(33.520/RT) (1,070∼1,250 ℃)
C + H₂O Reaction
kc₃=（(8.77×10⁸）/T^-1/2)․e^-(43.160/RT) (800∼1,000 ℃)
kc₃ = （(2.249×10⁶/ T^-1/2）․e^-(28.590/RT) (1,000∼1,150 ℃)
