What is the purpose of using two-stage reduction for platinum-tin catalysts in continuous reforming? I seek advice from experts
The upper part undergoes a reduction process, with low-temperature reduction being used to remove a large amount of moisture； The lower section involves two-stage reduction: high-temperature reduction is carried out under dry conditions, thereby ensuring an effective reduction effect while preventing the accumulation of catalyst metals and their deactivation due to high temperatures and high moisture levels.
That’s what the general manual says, but some people have suggested that it involves platinum reduction in the first stage and tin reduction in the second stage; I’m not sure if that’s correct
