ABSTRACT:
Gasifying liquid hydrocarbon fuels, and in particular liquid heavy hydrocarbon fuels, at high fuel-to-air equivalence ratios with no significant soot formation comprises the steps of mixing the fuel and heated air in a prevaporization and mixing zone to prevaporize only a portion of the liquid fuel using only the sensible heat in the air, passing the partially vaporized fuel-air mixture through a catalyst zone to catalytically combust at least some of the prevaporized portion of the fuel while simultaneously, without the use of an external heat source, vaporizing and gasifying as-yet unvaporized fuel using the additional heat generated by the catalytic combustion, wherein the length of the catalyst zone, the catalyst configuration, and the fuel flow rate have been preselected to obtain the desired amount of gasification and to sustain continuous gasification with no significant soot formation.
