摘要
研究了Ｎｉ－５和Ｎｉ－５－ＲＭ催化剂对ＣＨ４－ＣＯ２、Ｃ２Ｈ４－ＣＯ２和天然气－ＣＯ２转化制合成气的催化反应性能。发现Ｎｉ～５－ＲＭ催化剂对ＣＨ４－ＣＯ２转化不仅具有高的活性和选择性，而且具有良好的抗积炭性能和稳定性。该催化剂对天然气和ＣＯ２转化反应，通过加入极少量的消炭剂Ａ，不仅可以有效防止反应体系积炭，而且对催化活性和选择性基本没有影响。在８５０℃连续使用３００ｈ，产物合成气含量一直保持在９５．５％（ｍｏｌ）左右，催化剂活性无任何降低趋势。
The catalytical reactivities of Ni-5 and Ni-5-RM catalysts for reforming CH, C2H4.and natural gas with CO2, to produce syngashave been studied in the present pater. It wasfound that the Ni-5--RM catalyst not onlypossesses higher activity and selectivity, butalso has better resistance to carbon deposition. The Ni-5-RM catalyst did not deactivateat all during 240 hrs on stream for CH4-CO2reforming reaction. The addition of a few carboneliminator A into raw material gases notonly can avoid carbon deposition, but also hasfew influence on activity and selectivity. Itsactivity did not incline to reduce after continuous operation for 300 hrs with a .constantproduct syngas content at 95. 5 mol/%
