摘要

以经介质阻挡放电等离子体处理的SiO2为载体

用浸渍法制备了Ni/SiO2催化剂

并进行了CO甲烷化反应评价。与载体未经处理的常规Ni/SiO2催化剂相比

载体经处理的催化剂在400℃下的CO与H2转化率均提高了约6%

且在经700℃烧结6 h后

活性仍高于常规催化剂。XRD、TEM和H2-TPR结果表明

载体经处理的催化剂

Ni颗粒粒径更小、粒径分布更集中

Ni与SiO2之间的相互作用更强

证明等离子体处理使SiO2更有利于促进Ni的分散。

Abstract

Ni/SiO2 catalyst was prepared for CO methanation using SiO2 treated by dielectric barrier discharge plasma before impregnation.Compared with the conventional Ni/SiO2 catalyst without the treatment

the CO and H2 conversions at 400℃ were both approximately 6% higher for the support-treated catalyst.After the high temperature reaction at 700℃ for 6 h

the support-treated catalyst was still more active than conventional Ni/SiO2 catalyst.XRD

TEM and H2-TPR results showed that the support-treated catalyst had smaller Ni particle size and stronger interaction between Ni and SiO2

which confirmed that plasma treatment made SiO2 more favorable for Ni dispersion.
