Regenerating method and conditions:(1)Dehydration: molecular sieve is heated at 500-550°C for two hours,then cooled under air insulation,or molecular sieve is heated at 300-350°C for 2 hours under vacuum condition,then cooled under air insulation.
(2)Removing of organic materials: The over-heat inert gas with 200-350°C passes through the molecular sieve bed layer for certain time,then,the organic materials is deadsorbed and molecular sieve is regenerated.
(3)Removing of gaseous materials: Removed and generated under vacuum condition.
Precautions:
(1) Molecular sieve must be stored in close and dry place.If mositure adsorption,the regeneration is needed for use and the properties of molecular |
 |
sieve do not change.(2) The regenerating temperature can not be over 600°C,otherwise,its structure can be broken,the activity lost and adsorption performance decreased.
(3)The PH value of medium is 5-12.
