Study on Biomass Carbonization for Bio-Char Production

Bio-char with high fixed carbon yield is a potential material for barbecue and hot pot fuel. In the study, the effects of the process conditions including raw materials, carbonization temperature and residence time on the combustion characteristic of the resulted bio-char were investigated. Here, bio-char yield and combustion characteristic were used as evaluation indexes. It is foud out that the bio-char prepared from cotton stalk under the conditions of the final temperature of 500 oC and the residence time of one hour shows the best combustion characteristics.
