FBD型CO高变催化剂低汽气比性能及其工业应用

The low stream gas ratio characteristic and industrial application of FBD carbon monoxide HTS catalyst

介绍了FBD型CO高温变换催化剂的低汽气比性能和热稳定性.与B112型CO高变催化剂及国外同类型ICI71-4催化剂相比,FBD催化剂在低汽气比条件下具有更高的低温活性和热稳定性.工业使用情况表明:FBD型CO高变催化剂在低汽气比条件下能够长期运行,活性下降不明显,抗副反应能力很强.

In this study, the low stream gas ratio characteristic and thermal stability of FBD carbon monoxide HTS （high temperature shift） catalyst were presented. Comparing with B112 catalyst and abroad ICI71 - 4 catalyst, FBD catalyst possesses preferable low temperature activity and thermal stability at low stream gas ratio atmosphere. This was proved well when the catalyst was put into industrial application： it can keep high activity at low stream gas ratio atmosphere for long terms, and effectively restrain side reaction.
