A fast light-off catalytic reformer and method includes at least one preferably
substantially cylindrical reactor tube having an inlet for receiving a flow of
fuel and a flow of air, a reforming catalyst disposed within the reactor tube for
converting the fuel and air to a reformate stream, and an outlet for discharging
the produced reformate stream. An ignition device disposed within the reactor tube
initiates an exothermic reaction between the fuel and air. Heat generated thereby
provides fast light-off of the reforming catalyst. An associated control system
selects fuel and air flow delivery rates and operates the ignition device to achieve
fast light-off of the reforming catalyst at start-up and to maintain the catalyst
at a temperature sufficient to optimize reformate yield. The rapid production of
high yields of reformate is particularly suitable for use in an on-board reforming
strategy for meeting SULEV emissions with spark-ignition engines, especially with
larger, higher emitting vehicles.
