不钝化更换第一、三层低变触媒小结

Brief Sum Up of Replacement of First- and Third-Bed Low Temperature Shift Catalyst without Passivation

介绍了低变触媒在不钝化的情况下更换第一、三层的方法 ,并通过生产实践证明了其可行性。该方法既节约生产成本和时间 。

A method is described for the replacement of first and third bed low temperature shift catalyst without passivation, and it is proved to be feasible in production practice. The method not only reduces the production cost and time but also has no effect on the reduced second bed low temperature shift catalyst.
