通过均匀沉淀法制备了以锆-金属有机骨架化合物(Zr-metal organic framework,Zr-MOF)为载体的Ni/Zr-MOF催化剂,并用于湿污泥和秸秆混合催化热解实验。采用元素分析、X射线荧光光谱(XRF) 、热重分析(TG) 、X射线衍射(XRD) 、扫描电镜(SEM)和N_2吸附-脱附等温(BET)对载体和催化剂进行表征分析,通过一系列实验来探讨热解温度、秸秆添加量和Ni负载量对于湿污泥和秸秆混合催化热解制备富氢合成气的影响。结果表明,Zr-MOF载体颗粒均匀呈八面体,比表面积高达805.93 m~2/g,平均孔径为20.14 nm,为介孔结构。Ni/Zr-MOF催化剂具有较高的热稳定性和催化活性。与不添加催化剂相比,使用Ni/Zr-MOF催化剂在500 ℃...

The catalytic co-pyrolysis of wet sewage sludge and wheat straw for hydrogen-rich gas production was experimentally investigated in a fixed bed reactor with Ni/Zr-MOF catalyst. The Ni/Zr-MOF catalyst was characterized by ultimate analysis, XRF, TG, XRD, SEM and BET. The effects of reactor temperature, straw content and Ni loading on the composition and yield of gasification gases were explored. The experimental results indicate that the mesoporous Zr-MOF support particles are octahedral with a specific surface area of 805.93 m2/g and an average...
