PROCESS FOR THE PURIFICATION OF LINEAR PARAFFIN

摘要

A process for purifying linear paraffins in which a hydrocarbon stream containing linear paraffins contaminated with aromatics, sulfur-, nitrogen-, and oxygen-containing compounds, and color bodies, but essentially free of olefins, is contacted with a zeolitic solid absorbent such as a NaX zeolite or zeolite MgY. After absorption the zeolitic solid absorbent is desorbed with an alkyl-substituted aromatic desorbent such as toluene.
