摘要：Co-gasification is a promising approach to the clean and high-efficiency co-utilization of biomass and coal with syngas (H-2+CO) production. Gasification reactivity is an important factor influencing the operation conditions choice, carbon conversion efficiency and syngas production performance. Coal-biomass interaction during co-gasification will directly result in the synergy behavior of different forms and intensities on co-gasification reactivity. Due to the fuel origin diversity, structural property difference and reaction process complexity of biomass and coal, a clear understanding of reactivity characteristics and synergy behavior of co-gasification is very essential for revealing co-gasification reaction mechanism and providing theoretical support for actual application. In this paper, the influences factors (such as feedstock type, blended ratio, gasification temperature, co pyrolysis process, gasification reactor and biomass pretreatment) for co-gasification reactivity and the synergy behavior on co-gasification reactivity are summarized in details, and non-catalytic/catalytic synergy mechanisms for co-gasification are discussed. Previous researchers have acquired a plenty of meaning data, providing important reference for industrial application of co-gasification technology. However, volatile matter-char interaction mechanism during co-pyrolysis was still unclear, AAEM migration and transformation route during co-gasification are lack of in-situ analysis, transfer route and interaction of free radicals during co-gasification process were unknown, and co gasification kinetics model containing dynamic synergistic/inhibition factors hasn't been established.
