Drying Kinetics Characteristic of Indonesia lignite Coal(IBC) using Lab Scale Fixed Bed Reactor

摘要：

Recent instability of energy market arouse a lot of interest abour coal which has a tremendous amount of proven coal reserves worldwide.South Korea hold the second rank by importing eighty million tons of coal in 2007 following by Japan.Among various coals,there is disused coal.Its called Low Rank Coal (LRC).Drying process has to be preceded before being utilized as power plant.In this study,drying kinetics of LRC is induced by using a fixed bed reactor. G(a) =aNb/Re(L/D)kt The drying kinetics was deduced from particle size,the inlet gas temperature,the drying time,the gas velocity,and the L/D ratio.The consideration on reynolds number was taken for correction of gas velocity,particle size,and the L/D ratio was taken for correction packing height of coal.It can be found that active drying of free water and phase boundary reaction is suitable mechanism through the fixed bed reactor experiments.
