Fremgangsmåte for avvanning av organiske v¶sker

摘要

Process for dewatering organic liquids admixed with water wherein the admixture is brought into contact with a molecular sieve. The moleculat sieve is pretreated so as to reduce its acid site concentration and attain an ammonia TPD value of 18 mmol/g or less prior to contact with the admixture. The present invention relates to a process for dewatering organic liquids admixed with water, said process comprising bringing the admixture into contact with a molecular sieve, characterized in that the molecular sieve is pretreated so as to reduce its acid site concentration and attain an ammonia TPD value of 18 mmol/g or less prior to contact with the admixture.
