6. Study on steam gasification of coal-biomass briquette using waste coal (3)

Abstract

In this study, coal-biomass briquettes (BB) made by mixing waste coal and larch bark with Ca(OH)_2 as a sulfur fixation agent were pyrolyzed until 1173K in the inert atmosphere, and the obtained char samples were gasified under a stable steam generation at 1173K. As the result, an increased tendency of BB gasification was found with increment of the additive biomass. At the same time, total calorific values of produced gases are highly increased with the comparison of those produced from gasification of its original waste coal.
