Abstract
In this work, it was attempted to obtain kinetic data of gasification of anthracite which is needed for the design of fluidized mixed reactor for the sponge iron production.
Of a domestic anthracite （Bong Myung mines） rate equations of carbon monoxide formation under the temperature range from 800 ℃∼1200 ℃ were determined as follows ;
γ = kPCO2 / （1+KCOPCO+KCO2PCO2）
k = 1.32×10-2e-34,800/RT
KCO = 1.6e1,210/RT
KCO2 = 0.82915/RT
Over reaction rate and each constants were compared with that of Lewis1） et al. and of Yoo2) et al. numerically over the range of reaction conditions to distinguish the relative reaction characteristics of coals.
