Title:
C5~C8仕込原料または中間仕込原料の各々直鎖状パラフィン、1分枝パラフィンおよび多分枝パラフィンに富む3つの流出物への分離方法
Document Type and Number:
Japanese Patent JP4096114
Kind Code:
B2
Abstract:
For producing three effluents which are respectively rich in straight chain paraffins, in mono-branched paraffins, and in di-branched and tri-branched paraffins possibly with naphthenic and/or aromatic compounds, from C5-C8 cuts or intermediate cuts (C5-C7, C6-C8, C7-C8, C6-C7, C7 or C8), comprising paraffic and possibly naphthenic, aromatic and olefinic hydrocarbons, the separation process of the invention uses at least two separation units operating either by adsorption or by permeation. It is of particular application when coupled with a hydro-isomerization process, which selectively recycles straight chain and mono-branched paraffins, necessary with paraffins containing more than 7 carbon atoms.
