33. Reformation of Brown Coal by Hydro-thermal Treatment

Abstract

Reformation of the low quality coal by hydro-thermal treatment was conducted. Firstly, the coal was pulverized into moderate small powder. The coal slurry was prepared by mixing the pulverized coal and water. The coal slurry was filled in the pressurized reactor and then it was heated up 250C to 300C. The coal was reformed by this treatment and the liquefaction components were also obtained in this treatment process. The reformed coal were analyzed in this experiment.
