입자온도의 직접적인 측정법을 이용한 석탄촤 고압 CO2 가스화 반응률에 관한 연구

Gasification kinetics of coal char of coal Wira with CO2 at elevated pressure was investigated with a Pressurized Wire Heating Reactor(PWHR). An experimental method with the capacity to heat the coal char particle and measure its temperature directly (as with a thermocouple) was developed. The effects of gasification temperature(1100 ?. 1400oC), partial pressure of carbon dioxide(0.2 ?. 0.8), and total pressure(10 ?. 30atm) on gasification rate of the coal char with CO2 were determined. The modified nth-order reaction models were then employed to analyze the reaction kinetics.
