ABSTRACT:
Aromatic hydrocarbons present in a hydrocarbon feed stream containing a mixture of aromatic hydrocarbons and non-aromatic saturated organic components are separated from said hydrocarbon feed stream by selective permeation of the aromatic hydrocarbon through a regenerated cellulose or cellulose acetate membrane which has been impregnated with polyethylene glycol. The thus treated membrane possesses high selectivity for aromatic hydrocarbons at a high flux. The amount and type of polyethylene glycol impregnated into the membrane is carefully controlled in order to achieve high aromatic selectivity and high flux.
