摘　　要：本研究是利用热重分析仪(TGA)和扫描电镜对脱墨污泥热解特性及生物质半焦孔隙结构特性进行表征,探讨脱墨污泥热解特性及其合理利用途径。研究结果表明,脱墨污泥的热解分为两个阶段,即脱挥发分阶段及碳化阶段。随着热解温度的升高,脱墨污泥焦颗粒表面孔隙增加、孔隙变大。The thermogravimetric analyzer and scanning electron microscopewere used to characterize the pyrolysis characteristics of deinking sludge and the pore structure characteristics of its coke.The pyrolysis characteristics of deinking sludge and its rational utilization methods were discussed.The results show that the pyrolysis of deinking sludge is divided into two stages:the devolatilization stage and the carbonization stage.With the increase of pyrolysis temperature,the surface pores of deinking sludge coke particles increase and the pores become larger.
