Claim 1
Independent Claim
87 words
A PROCESS FOR THE HYDROCATALYTIC DESULFURIZATION OF PETROLEUM HYDROCARBONS BOILING IN THE GAS OIL RANGE, WHICH COMPRISES PASSING THE HYDROCARBONS AT A SPACE VELOCITY OF THE LIQUID FEEDSTOCK WITHIN THE RANGE 0.5 TO 20 Y./V./HR. AND IN ADMIXTURE WITH UP TO 2000 S.C.F./B. OF HYDROGEN OVER A SULFUR-RESISTANT HYDROGENATION CATALYST AT A TEMPERATURE OF 750-820*F. AND A PRESSURE OF ABOVE 500 P.S.I.GA. AND NOT EXCEEDING 1000 P.S.I.GA., WHEREBY ORGANICALLY COMBINED SULFUR IN THE HYDROCARBONS IS CONVERTED INTO HYDROGEN SULFIDE, AND REMOVING HYDROGEN SULFIDE FROM THE TREATED HYDROCARTONS.
