Process for separating normal paraffins from branched and cyclic hydrocarbons.

摘要

Normal paraffins are separated from mixtures of the same with cyclic hydrocarbons having more than six carbon atoms per molecule and/or branched chain hydrocarbons by contacting the mixture at adsorption conditions with an adsorbent comprising silicalite, whereby the normal paraffin is selectively adsorbed. It may then be recovered from the adsorbent by desorption with a desorbent material. Preferably a simulated moving bed countercurrentflowadsorption system is used.
