TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Substrate: The ultra-short-channel-length metal substrate is in the form of stacked or coil metal mesh. Preferred Process: The contacting process is carried out in the oxygen/carbon mol ratio of 0.6:1-1.3:1, and steam/carbon ratio of 0.8:1-1.3:1, at temperature at the outlet of the catalyst bed of more than 650 degrees C and less than the peak catalyst temperature. The contacting process is conducted at gas hourly space velocity of combined feeds of liquid hydrocarbon fuel, oxidant, and water or steel of more than 10000 hour-1 and less than 250000 hour-1. The peak catalyst temperature is measured at the surface of the catalyst, and at the distance form 5-50% measured along the length of catalyst bed from inlet to outlet. The reformate stream is further fed to a heat exchanger to reduce its temperature to 300-600 degrees C, and contacted with a sulfur adsorbent, such that desulfurized reformate stream comprising carbon monoxide, hydrogen and sulfur having concentration of less than 5 volume ppm. Preferred Condition: The peak catalyst temperature is preferably more than 950 degrees C to less than 1050 degrees C. Preferred Composition: The concentration of sulfur in the liquid fuel is preferably more than 100 weight ppm and less than 375 weight ppm. The oxidant is air, preferably pure oxygen, oxygen-enriched nitrogen and oxygen-enriched inert gas. The reformate steam further comprises low molecular weight sulfur compound(s) in concentration of more than 3 volume ppm and less than 40 volume ppm. The low molecular weight sulfur compound is chosen from hydrogen sulfide, carbonyl sulfide and/or sulfur dioxide. The total concentration of hydrogen and carbon monoxide in the reformate stream is more than 30%. The total concentration of coke precursor in reformate stream is less than 150 volume ppm. Preferred Properties: The low molecular weight sulfur compound has molecular weight of less than 90 g/mol. The reforming efficiency is more than 70%, during reformation of sulfur-containing liquid fuel.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Property: The organosulfur compound(s) have molecular weight of 90 g/mol or more.
