摘　　要：综述了温度、压力、催化剂和产物中CO的浓度等因素对生物质在CO2气氛中气化的影响。提高反应温度可以明显增加反应速率;压力的作用较复杂,反应过程中不仅受总压力的影响还受到反应物分压的影响;碱金属元素和碱土金属可以促进反应;根据反应机理,气体中CO含量过高会抑制反应的进行,减少反应中CO的分压和含量可以促进反应。展望了生物质CO2气化的应用前景。The effect of temperature,pressure,catalyst and the concentration of monoxide on biomass carbon dioxide gasification was reviewed.With the increment of temperature,the reactivity of biomass was accelerated dramatically.The effect of the pressure was complex for the reaction of gasification.It was influenced both by partial pressure of components and the whole pressure.Alkali metal and alkali earth metal can be used as catalysts for accelerating the reaction of biomass carbon dioxide gasification.According to the mechanism of carbon dioxide gasification,increasing the amount of monoxide inhibits the reaction to the favorable side.However,reducing the partial pressure and the amount of monoxide in the syngas can promote the reaction rate.The prospect of biomass carbon dioxide gasification application was also presented.
