Hydrogen Production from Liquid Hydrocarbons Demonstration Program

摘要

The Air Force now uses diesel engine generators as sources of heat and electricity at selected remotes sites. Simultaneously, it has investigated alternative cogeneration candidates that offer improved reliability, maintain ability, and economics. One system that shows high potential is a phosphoric acid fuel cell (PAFC) power plant consisting of a fuel conditioner to convert logistic fuels such as DEF-2, DF-a and JP-4 to a hydrogen-rich gas, and a power conditioner to convert the direct current power to alternating current. The objective of the project work was to define, and demonstrate, a fuel conditioner to meet performance criteria established for the Air Force Remote Site Fuel Cell Power Plant program. Key criteria included high fuel-to-hydrogen conversion efficiency, rapid startup and load following capability, and minimum water consumption during operations. A process configuration which has the potential to produce a minimum of 0.365 pound of hydrogen per pound of feed diesel consumed is described. The hydrogen-containing product is a suitable fuel for phosphoric acid fuel cell power plant. A 2 mole per hour (hydrogen) demonstration plant was designed, constructed and started up. Results are summarized.
