Effect of heating rate and steam partial pressure on char gasification reactivity in Shenhua coal char and its maceral concentrates

Gasification reactivity of Shenhua coal char and it's maceral concentrates was investigated by non-isothermal thermogravimetiy. Effect of different heating rates and steam partial pressures on char gasification reactivity was analyzed. Gasification reactivity of samples was estimated based on maximum reaction rate and half-life. Results indicated gasification reactivity order of Shenhua char is vitrinite char raw char inertinite char in different heating rate and partial pressure under same gasification process.
