介质阻挡放电等离子体处理载体对CO甲烷化Ni/SiO2催化剂性能的改进
Ni/SiO2 catalyst for CO methanation with support treated by dielectric barrier discharge plasma
摘要
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'C 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.关键词
