摘　　要：为探究生物质原料和热解温度对生物质炭理化特性的影响,文章分别对松子壳、油茶壳、木屑和稻壳进行连续热解试验,获得生物质炭产物。通过对生物质炭的产率、工业分析与热值、吸附值、孔隙结构及表面官能团等理化特性的全面表征,研究原料种类及热解温度对生物质炭理化特性的影响。研究结果表明:松子壳炭、油茶壳炭、木屑炭的热值均大于标准热煤的热值;原料的挥发分含量越高,生物质炭的产率就越低,原料的灰分含量与生物质炭的灰分含量的变化趋势相一致;当热解温度为500℃时,4种生物质炭均可以形成较丰富的中、大孔隙结构,但松子壳、油茶壳等硬壳类生物质炭的微孔更为发达;随着热解温度的升高,生物质炭产率不断下降,生物质炭所含官能团的种类发生变化,数量逐渐减少,孔隙数量也减少,生物质炭的吸附能力减弱。In order to analyze the physical and chemical properties of biomass carbon under various pyrolysis temperature,continuous pyrolysis experiments were carried out to obtain biomass carbon products using pine nut shell,camellia oleifera shell,sawdust and rice shell as raw materials.The physicochemical properties of biomass carbon were analyzed including productivity,industrial analysis,calorific value,adsorption value,pore structure and surface functional groups.The findings show that the calorific values of pine nut shell carbon and camellia oleifera shell carbon and sawdust carbon are greater than those of standard hot coal.The higher the volatile content of raw materials,the lower the productivity of biomass carbon,and the ash content of raw materials is consistent with that of biomass carbon.When the pyrolysis temperature is 500℃,biomass carbon can form rich medium and large pore structures,but pine nut shell and camellia oleifera shell have more micropores.With the pyrolysis temperature increasing,the productivity of biomass carbon continues decreases,the species and the number of functional groups of biomass carbon gradually decreases,thus the adsorption capacity of biomass carbon decreases.
