51 廃棄石炭利用バイオブリケットのガス化へのバイオマス混合粒径の影響(バイオマス)

抄録

In this study, to shorten gasification reaction time of waste coal-biomass briquette, different sizes of mixing biomass in making waste coal-biomass briquette were used. After the pyrolysis, the gasification experiment was conducted with waste coal-biomass briquette char under the temperature of 900℃ and H_2O/Ar mixture gas. As a result, gasification reaction time of waste coal-biomass briquette char was shorter. It was assumed that ash contents in biomass worked as the gasification catalysts were dispersed, and also specific surface area was increased in the char.
