SAETT ATT SEPARERA NORMALA KOLVAETEN FRAN EN FLYTANDE KOLVAETEBLANDNING,SOM INNEHILLER NORMALA OCH FOERGRENADE ALIFATISKA OCH CYKLISKN KOLVAETEN

摘要

Normal aliphatic hydrocarbons are separated from mixtures containing them by preferential adsorption on a molecular sieve followed by desorption with a different normal aliphatic hydrocarbon while maintaining on the sieve 0.5-4% by weight of water. The water content of the feed or desorbent is adjusted to maintain a constant concentration of water in the fluid contacting the sieve of about 30 p.p.m. The procedure of Specification 879,687 may be used. The process may be applied to separating normal hydrocarbons from naphtha, jet fuel and lubricating oils.ALSO:Normal aliphatic hydrocarbons are separated fom hydrocarbon mixtures by preferential adsorption on a zeolite molecular sieve followed by desorption with a different normal aliphatic hydrocarbon wqhile maintaining on the sieve 0.5-4% by wt. of water.
