Process for paraffin isomerization with liquid phase adsorptive product separation and with direct recycle of extract stream.

摘要

A hydrocarbon stream comprising linear hydrocarbons is fed to an isomerization reactor, to which a recycle stream comprising linear hydrocarbons and desorbent is fed. The effluent of the isomerization reactor is fed to an adsorption zone in which the linear hydrocarbons are selectively adsorbed. A desorbent is used to desorp these linear hydrocarbons and the resulting stream is the above recycle stream.
