CO低温变换催化剂的还原过程分析

The Process Analysis for The Reduction of Low Temperature Shift Catalysts

铜锌铬系和铜锌铝系两种催化剂配合使用,既可增强低变催化剂的抗中毒能力,延长催化剂和使用寿命,又可以使低变炉出口的CO降低,催化剂的还原主要用氢气,分四个过程。

The combined use of both copper-zink-chromium series and copper-zink-aluminum series of LT shift catalysts can not only increase the anti-poisoning ability of LT shift catalyst and extend its service life,but also reduce CO at LT shift furnace outlet.The catalyst is mainly reduced by the use of hydrogen in four steps.
