THE METHOD OF CONVERTING A HYDROCARBON GAS COMPOSED ESSENTIALLY OF PROPANE, AND INCLUDING RESIDUAL AMOUNTS OF PARAFFINS OF HIGHER AND LOWER MOLECULAR WEIGHT, TO ISOPARAFFINS OF HIGHER MOLECULAR WEIGHT THAN PROPANE, WHICH COMPRISES HEATING SAID PROPANE IN GASEOUS PHASE TO A TEMPERATURE IN THE RANGE OF ABOUT 400* F. TO ABOUT 2000* F., PASSING SAID HEATED PROPANE GAS THROUGH A ZONE SUBJECTED TO A SUPERIMPOSED HIGH POTENTIAL ELECTROSTATIC FIELD AND AN OSCULLATING ELECTROMAGNETIC FIELD OF A FREQUENCY IN THE RANGE BETWEEN 40 AND 300 CYCLES PER SECOND, COOLING THE GASEOUS MATERIAL SO TREATED AND WITHDRAWING A MIXTURE HAVING AN INCREASED CONTENT OF HYDROCARBONS OF A HIGHER MOLECULAR WEIGHT THAN THE ORIGINAL PROPANE.
