Regenerating method and conditions:
(1)Dehydration:molecular sieve is heated at 500-550℃for two hours,then cooled under air insulation,or molecular sieve is heated at 300-350℃for 2 hours under vacuum condition,then cooled under air insulation.
(2)Removing of organic materials:The over-heat inert gas with 200-350℃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 moisture adsorption,the regeneration is needed for use and the properties ofmolecular sieve do not change.
(2)The regenerating temperature cannot be over 600℃,otherwise,its structure can be broken,the activity lost and adsorption performance decreased.
(3)The pH value of medium is 5~12.
