Molecular sieve regeneration temperature

ASU conventional 13X molecular sieves general use above 700 degrees will produce degeneration, but his regeneration temperature of 140 degrees can be, that is, blowing cold temperature can reach this peak, but we do ASU around 180 degrees heating gas for heating to him, in order to ensure the peak cold blow to ensure complete regeneration. The temperature there is sufficient, at higher is a waste of energy. At the end of the cold blowing temperature should be at room temperature, below 30 degrees, or molecular sieve adsorption capacity is not restored to the best. Because the lower temperature molecular sieve adsorption capacity of the stronger. Whether complete regeneration of molecular sieves flag is blowing cold blowing cold peak, cold blowing peaking at 140 degrees can be considered very thoroughly heated, the next is to ensure that the outlet temperature of the cold end of the blow.
