A PROCESS FOR STEAM REFORMING OF HYDROCARBONS COMPRISING REACTING A LIQUEFIED PETROLEUM HYDROCARBON BOILING BELOW 200*C. AT ATMOSPHERIC PRESSURE, AND STREAM, OVER A NICKEL STRAM REFORMING CATALYST, AND STREAM, OVER A STREAM RATIO OOF FROM ABOUT 2.5 TO 6 MOLES OF STEAM PER ATOM OF CARBON, AND WHEREIN A CONTROLLED AMOUNT OF SULPHUR IS ADDED TO THE HYDROCARBON SO AS TO MAINTAIN THE SULPHUR CONTENT OF THE OVERALL HYDROCARBON FEED AT A RANGE OF FROM ABOUT 1 TO ABOUT 10 P.P.M. BY WEIGHT, SAID ADDED SULPHUR BEING IN THE FORM OF ORGANICALLY COMBINED SULPHUR OCCURRING IN A PETROLEUM HYDROCARBON.
