| ExxonMobil's Pressure Swing Reforming (PSR) technology can potentially overcome many of the disadvantages of ATR (e.g. start-up time and energy input) and conventional steam reforming (e.g. metallurgy limitations) for onboard hydrogen generation. PSR utilizes a cyclic reverse flow reactor consisting of two distinct steps. During the regeneration step, the reactor is heated by combusting a gaseous fuel. During reforming, a hydrocarbon fuel is catalytically steam reformed in the hot zone created by regeneration. ExxonMobil has developed a prototype dual-bed PSR to demonstrate the direct steam reforming of commercial liquid fuels. We have achieved >1000 hours of operation and our latest reactor design can achieve >99% conversion of carbon to CO + CO2. This paper will discuss the performance we have achieved with our PSR prototype, as well as our long-term goal of demonstrating an integrated fuel processor that is capable of producing hydrogen onboard a vehicle to supply hydrogen to a fuel cell. |
