Synthetic molecular sieve
Thread Content
Is molecular distillation used in any of the synthesis processes? Is it better to use molecular sieves after ammonia cooling, or after the circulation machine?
Original poster, please clarify the conditions or specify the technical requirements so that others can give you advice. Your title is incorrect. Upon reading it, one can understand the principles behind the synthesis of molecular sieves, as well as the methods used for their synthesis.

It should be after ammonia cooling. The moisture is brought in by the fresh gas.
Between the circulators, freezing is likely to occur after the ammonia cooler
