【摘要】 通过ＸＰＳ、ＦＴ－ＩＲ及催化剂性能测定，Ｂ１２１型无铬高变催化剂加入的Ｂ助剂有２／３以氢氧化物形态存在，增加了催化剂表面ＯＨ－１浓度，提高变换反应速率．使催化剂在低汽气比下仍具有高活性，０３汽气比下活性优于Ｂ１１２、ＩＣＩ７１－４，并未发现Ｆ－Ｔ副产物生成．工业使用表明，Ｂ１２１型催化剂最佳使用汽气比为０４６，与一般高变催化剂相比，汽气比低约０１５，节能效果显著．更多还原

【Abstract】 It is inferred by the measuring of XPS、FT-IR and catalytic properties that 2/3 of prompter B added in B121 type free-chrome HTS catalyst exist as hydroxide, with which the concentration of OH - on the surface and reaction velocity increasea, and results in the catalyst having high activity at low v/g ratio. It is shown that the catalytic properties of B121 prior to B112、ICI71-4 while the v/g ratio is 0 3 , and no F-T byproduct is found in the reaction product. Industrial use of B121 shows that the optimist v/g ratio is 0 46 . Compared with the original catalyst, B121 has significant effect on power saving with v/g ratio decreasing by 0 15.更多还原
