A METHOD OF TREATING A HYDROCARBON STREAM CONTAINING STRAIGHT CHAIN HYDROCARBONS AND NON-STRAIGTH CHAIN HYDROCARBONS WHICH COMPRISES CONTACTING SAID STREAM WITH A SOLID PARTICEL-FORM SELECTIVE ADSORBENT WHICH SELECTIVELY ADSORBS STRAIGHT CHAIN HYDROCARBONS TO THE SUBSTANTIAL EXCLUSION OF NON-STRAIGHT CHAIN HYDROCARBONS TO ADSORB STRAIGHT CHAIN HYDROCARBONS THEREFROM, THEREBY PRODUCING A TREATED EFFUENT HAVING A REDUCED AMOUNT OF STRAIGHT CHAIN HYDROCARBONS, SEPARATING SAID SOLID ADSORBENT, NOW CONTAINING STRAIGHT CHAIN HYDROCARBONS ADSORBED THEREIN, FROM SAID TREATED EFFUENT, CONTACTING SAID SEPARATED SOLID ADSORBENT WITH A GASEOUS DESORBING MEDIUM IN THE PRESENCE OF A POROUS FIXED MASS OF PARTICLEFORM CATALYTIC MATERIAL UNDER CONDITIONS TO EFFECT DESORPTION OF SAID STRAIGHT CHAIN HYDROCARBONS FROM SAID ADSORBENT AND CATALYTIC CONVERSION OF THE RESULTING DESORBED STRAIGHT CHAIN HYDROCARBONS WHEREBY THE RESULTING REGENERATED ADSORBENT TOGETHER WITH THE CONVERTED DESORBED STRAIGHT CHAIN HYDROCARBONS AND GASEOUS DESORBING MEDIUM PASS THROUGH THE INTERSTICES OF SAID FIXED BED OF CATALYST, RECOVERING FROM THE AFOREMENTIONED DESORPTIONCONVERSION OPERATION A RELATIVELY DILUTE GAS-SOLIDS PHASE COMPRISING CONVERTED HYDROCARBONS, GASEOUS DESORBING MEDIUM AND SAID REGENERATED ADSORBENT SUBSTANTIALLY FREE OF SAID CATALYST, AND SEPARATING SAID ADSORBENT FROM SAID DILUTE GAS-SOLIDS PHASE.
