摘要

前期工作表明Ni/Si3N4催化剂在甲烷部分氧化反应中有较好的催化活性和很强的抗积炭能力。在前期工作的基础上考察了镍负载量和焙烧温度对Ni/Si3N4催化剂在甲烷部分氧化中催化性能的影响，并采用XRD、TPR、XPS等技术对催化剂进行了表征。结果表明，镍负载量和焙烧温度影响催化剂活性组分的表面分布和晶粒尺寸，并进一步影响催化剂的反应性能。在800℃反应条件下，活性组分负载量与CH4转化率之间的关系为：C-10>C-15>C-5>C-1；而焙烧温度与CH4转化率大小顺序为：S(400)> S(600)>S(800)。

Abstract

In a previous study

high activity of Ni/Si3N4 catalyst，high selectivity and remarkable resistance to coke formation in partial oxidation of methane (POM) were reported.This work is part of a broad investigation seeking nickel catalysts supported by silicon nitride with high catalytic performance for POM.The effects of nickel loading and calcination temperature on the catalytic performance were investigated with XRD，TPR and XPS.The characterization results suggested that the nickel loading and calcination temperature affected the catalyst performance via influencing surface distribution and crystallite size of active components strongly.The order of methane conversion of Ni/Si3N4 catalysts with different nickel loadings and calcination temperatures was C-10>C-15>C-5>C-1 and S(400)>S(600)>S(800) respectively.
