A METHOD OF FRACTIONATING A PETROLEUM MIXTURE CONSISTING ESSENTIALLY OF STRAIGHT CHAIN HYDROCARBONS AND NONSTRAIGHT CHAIN HYDROCARBONS HAVING AT LEAST 5 CARBON ATOMS PER MOLECULE, WHICH COMPRISES INCORPORATING IN SAID PETROLEUM MIXTURE A STRAIGHT CHAIN HYDROCARBON CONTAINING LESS THAN 5 CARBON ATOMS PER MOLECULE, CONTACTING THE RESULTING MIXTURE WITH AN ALUMINO-SILICATE MOLECULAR SIEVE TYPE ADSORBENT WHICH SELECTIVELY ADSORBS STRAIGHT CHAIN HYDROCARBONS TO THE SUBSTANTIAL EXCLUSION OF NON-STRAIGHT CHAIN HYDROCARBONS UNDER CONDITIONS TO EFFECT THE ADSORPTION OF SAID STRAIGHT CHAIN HYDROCARBONS FROM SAID ADMIXTURE WHEREBY SAID MOLECULAR SIEVE ADSORBENT BECOMES SUBSTANTIALLY SATURATED WITH STRAIGHT CHAIN HYDROCARBONS CONTAINING AT LEAST 5 CARBON ATOMS PER MOLECULE AND LESS THAN 5 CARBON ATOMS PER MOLECULE AND DESORBING SAID ADSORBED STRAIGHT CHAIN HYDROCARBONS FROM SAID ADSORBENT, BY CONTACTING SAID ADSORBENT WITH SAID STRAIGHT CHAIN HYDROCARBON CONTAINING LESS THAN 5 CARBON ATOMS PER MOLECULE.
