United Technologies Corporation, in cooperation with the |
|
Electric Power Research Institute, has developed an |
|
adiabatic steam reformer capable of processing sulfur- |
|
containing fuels for commercial fuel cell power plants. |
|
No. 2 fuel oil and various coal-derived liquids have |
|
recently been successfully reformed to hydrogen using |
|
advanced catalyst formulations. The objective of this |
|
program is to determine the performance of the adiabatic |
|
reformer when operated with military logistic fuels. The |
|
test data will form the basis for system evaluation of |
|
the use of the adiabatic reformer in Army 'SLEEP' power |
|
plants using military logistic fuels. A two-inch diameter |
|
adiabatic reformer capable of supplying the hydrogen |
|
required for a 2.5 kW to 6 kW power plant was loaded with |
|
advanced metal oxide and nickel catalysts. It ran over |
|
1400 hours; 840 hours with No. 2 fuel oil as reference |
|
fuel, 350 hours on unleaded gasoline, and 216 hours on |
|
diesel fuel. The performance of the reformer on No. 2 |
|
fuel oil (for calibration against previous tests) closely |
|
matched previous tests both with respect to fuel |
|
conversion and carbon formation characteristics. After an |
|
initial decay period of about 200 hours, the performance |
|
remained stable for the remaining 1200 hours of test. The |
|
reformer operated at conditions set as design goals for a |
|
commercial fuel cell power plant. With unleaded gasoline, |
|
the tendency for carbon formation was greatly reduced; |
|
even at the lowest values for oxygen to carbon ratio in |
|
the process steam no carbon was detected. Operating |
|
parameters were defined for each of the fuels. The effect |
|
of steam/carbon ratio, pressure and fuel flow rate on |
|
fuel conversion was determined. |
