In order to explore the characteristics and mechanism of biomass partial gasification for biochar and syngas coproduction in the fluidized bed, a study on the influence of gasification performance and biochar characteristics after partial gasification with different air equivalence ratios was carried out in a self-built small atmospheric bubble fluidized bed. The results indicate that […]

Chemical looping ammonia generation (CLAG), efficiently converting C-based material, N-2 and H2O into NH3 and CO, is considered to be one of the promising NH3 production technologies. Using biochar as the C-based material is supposed to further improve the green level of NH3 but there is rare report about that. This paper was desired to […]

Low biodegradation poses significant challenges to widespread adaptation of anaerobic digestion (AD) technology mainly attributed to low biogas yield. The biodegradation of organic substrate can be increased by enhancing direct interspecies electron transfer (DIET) by adding laterite mineral and biochar to the AD system. This study evaluates the efficiency of Laterite-mineral (LM), biochar (BC) and […]

Taking the production process of sludge-based biochar as the research object, based on the measured data of engineering field operation, the thermal balance models of sludge carbonization and cooling conveying system, pyrolysis gas incineration and waste heat recovery system, flue gas treatment and deodorization system were established respectively. The energy loss points in the process […]
