摘要：Biomass and coal co-pyrolysis is one of most important reactions in the co-combustion and co-gasification of them. In order to study the interaction of biomass and coal in the co-pyrolysis process, thermo gravimetric experiments of them under different mixing modes were make. The mixed modes of biomass and coal include uniformly mix and stratified layout (coal in the upper) and stratified layout (biomass in the upper). The experimental results show that: the temperature of co-pyrolysis is lower than that of coal pyroly sis separately; the co-pyrolysis reaction velocity would be accelerated or debased, that depends on the biomass components and the mixing modes; the co-pyrolysis reaction velocity of coal and sawdust would be accelerated under the condition of uniformly mix; the others would be debased. The experimental results show also that: the reaction velocities of biomasses and coal co-pyrolysis always are less than those of separately pyrolysis. This study provides the important reference and theoretical basis for biomass and coal co-combustion and co-gasification.
