Abstract
A liquid fuel reformer includes a fuel vaporizer which utilizes heat from an upstream source of heat, specifically, an electric heater, operable in the start-up mode of the reformer, and therefore independent of the reforming reaction zone of the reformer, to vaporize fuel in a downstream vaporization zone.
Claims16
A method of reforming a liquid reformable fuel, the method comprising:
- introducing a stream of an oxygen-containing gas into a conduit configured to route fluids into an inlet of a reformer that produces a heat of exotherm during reforming of the reformable fuel;
- in a start-up operating mode, heating the stream of the oxygen-containing gas with a first source of heat comprising an electric heater disposed in the conduit;
- beginning a steady-state operating mode after a selected temperature of the reformer is reached and in the steady-state operating mode, heating the stream of oxygen-containing gas in the conduit with a second source of heat to the conduit comprising the heat of exotherm from the liquid fuel reformer and/or a hydrogen reformate-consuming device external to the liquid fuel reformer to provide a stream of heated oxygen-containing gas;
- introducing into the stream of oxygen-containing gas that had been heated by the first or second source of heat, through or proximate to a vaporizer, a vaporized liquid reformable fuel and mixing the vaporized liquid reformable fuel with the heated oxygen containing gas to provide a heated gaseous reforming reaction mixture;
- and
- reforming the heated gaseous reforming reaction mixture to produce a hydrogen-rich reformate and the heat of exotherm.

A method of steam reforming a liquid reformable fuel, the method comprising:
- generating steam with a source of heat selected from an electric heater, heat of exotherm of a reforming reaction and heat from a hydrogen reformate consuming device;
- introducing a stream of the steam through or proximate to a liquid reformable fuel vaporizer to provide a heated gaseous steam reforming reaction mixture;
- and
- reforming the heated gaseous reforming reaction mixture to produce a hydrogen-rich reformate.
