| 摘 要： | 采用等体积浸渍法制备了不同助剂 (Fe, Mg, Mn 和 Ce) 修饰的镍-凹凸棒石粘土基催化剂 (Ni/PG), 并用于催化裂解生物质气化焦油反应. 采用 X 射线衍射和透射电子显微镜对 Ni/PG 催化剂进行了表征, 并用总碳分析仪测定了催化剂上的积炭. 结果表明, 助剂的种类及其含量对催化剂性能的影响显著, 在所选用的助剂中, Fe 助剂入最有利于提高 Ni/PG 催化剂上焦油的去除率和 H2 的收率, 且随助剂 Fe 含量的增加, 催化剂活性逐渐提高.

| Abstract: | The Ni-based catalyst with the Fe additive showed high tar removal because of interaction of nickel oxides and iron oxides on palygorskite (PG). The tar removal of 99.0% was obtained over 8%Fe-6%Ni/PG, which was 34.6% and 30% higher than 6%Ni/PG and 8%Mn-6%Ni/PG, respectively. |
