负载型镍催化剂的抗积炭性能

The Performance of Resistance to Carbon Deposition of Supported Nickel Catalyst

本文初步研究负载型镍催化剂在ＣＨ４与ＣＯ２转化制合成气中的抗积炭性能．实验结果表明，ＭｇＯ，Ｌａ２Ｏ３的添加可改善ＮｉＯ／Ｙ—Ａｌ２Ｏ３催化剂的抗积炭性能和稳定性，催化剂表面ＣＯ的歧化反应是导致积炭的原因之一．

This paper primarily studies the performance of resistance to carbon deposition e of supported nickel catalyst on conversion of CH4 and CO2 in producing synthetic gas.The experimental result shows that MgO and La2O3 doped NiO/Y-Al2O3 catalyst can improve the resistance to carbon deposition and reaction stability. CO disproportionation on thesurface of catalyst may be one of the reasons for carbon deposition.
