摘要
The 10%Ni/Al_2O_3 catalyst for partial oxidation of methane was treated byDBD (dielectric barrier discharge) plasma in a continuous system under atmospheric pressure and roomtemperature by flowing He. It was found that 10%Ni/Al_2O_3 catalyst treated by plasma presents ahigher catalytic activity and an enhanced stability than the catalysts prepared without plasmatreatment. The methane conversion over the catalyst treated by plasma is 3%-5% higher than thecatalysts untreated by plasma. Moreover, the enhanced dispersion of the catalyst can be achieved byplasma treatment, which can improve the interaction between active species and supports, catalyticactivity and the resistance to carbon deposition.
