Study on Biomass Carbonization for Bio-Char Production

Abstract

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.

Research on the optimum carbonization process of walnut shell based on dynamic analysis

“…Meanwhile, the density of biomass carbon increased, and the hydrophobicity of biomass carbon improved. 13 We can be seen that the quality and energy loss during the carbonization process increase with the initial biomass water content, and the calorific value of biomass materials is significantly improved. As the holding time increases, the decomposition amount of biomass components gradually increases, and the carbonization rate decreases.…”
