8/3/2019 ATR Performance for Liquid Fuel Applications
The concept of autothermal reforming implies that heat produced by exothermicreactions is used by endothermic reactions with the condition that the heatexchange occurs within the same process flow without being separated by a heattransfer barrier.
The obvious advantage is the simplicity of design and the absence of heat transferhardware, therefore a better thermal efficiency.

•Precious metal catalyst on alumina•kinetic volume: 240 cc•100 SLPM total flow•GHSV = 25,000 h-1

• Incorporate integral heat exchanger into ATR structure in order to vaporize liquid fuel+H2Omixture (utilizing energy released at the catalytic wall) and control product temperature at ATRexit
• Ease of manufacturing (quick and inexpensive manufacturing process utilizing conventionalmachining)
• Line of sight to catalyst wall for easy catalyst application and subsequent inspection
• Minimize thermal mass of ATR reactor structure (for fast start-up) and minimize temperature
gradients across reactor height (structural and flowpath integrity implications)
• Design concept can be used to complete the fuel reforming process by allowing integrationwith desulfurization unit, WGS, and PROX reactors
• ATR reactor structural material compatibility with catalyst coat and steady-state operationalpeak temperature of 1,000ºC (1800ºF)

oxidation (as indicated by the presence of CO2and consumption of O2)
• Light-off takes place in the back-end of thecatalyst bed and propagates upstream to thefront-end.
• Syngas is detected only after light-off andpropagation.
• Constant temperatures in the fuel deliverysystem - fuel mix ignition prior to reactor(residence time of flammable mixture in the fueldelivery system is shorter than the ignition delaytime for JP-8)
