Aspen Products Group, Inc. (APG) has successfully completed acceptance testing and delivery of its second logistic fuel processor prototype. The prototype, shown in the attached photograph, is an advanced thermally integrated fuel processor that employs a regenerable desulfurization subsystem and catalytic partial oxidation reformer to produce reformate suitable for use with a solid oxide fuel cell. Highlights of the recent testing include:

• operation on JP-8 and commercial diesel (JP-8 containing 1000 ppmw sulfur was provided by the Air Force from its logistic                fuel supply),
• automatic operation on either fuel,
• production of greater than 10 kWth (based upon the LHV of H2 and CO) of reformate at an efficiency of 77%, and
• production of reformate that contains greater than 22 vol% H2 and 23 vol% CO

Advancements to the prototype system resulted in system simplification and reduced weight and volume compared to the earlier prototype. The AFRL prototype fuel processor operated automatically through start up, rated power, regeneration of internal sulfur removal beds, and shut down at APG’s facilities. The fuel processor has been delivered to Wright-Patterson AFB, OH for additional independent testing by the Air Force.
