Claim 3
Independent Claim
75 words
A METHOD OF REMOVING SULFUR FROM PETROLEUM HYDROCARBONS CONTAINING RELATIVELY COMPLEX SULFUR COMPOUNDS WHICH COMPRISES SUBJECTING SAID HYDROCARBONS TO CONTACT WITH A SUBSTANTIAL AMOUNT OF HYDROGEN IN THE PRESENCE OF HYDROGENASE-PRODUCING MICROORGANISMS SELECTED FROM THE GROUP CONSISTING OF DESULFOVIBRIO DESULFURICANS AND SPOROVIBRIO, EFFECTING SAID CONTACT IN THE PRESENCE OF A NUTRIENT MEDIUM FOR SAID MICROORGANISMS WHEREBY SULFUR IS SPLIT FROM SAID COMPLEX COMPOUNDS IN THE FORM OF GASEOUS PRODUCTS AND REMOVING SAID GASEOUS PRODUCTS THEREFROM.
