Performance of a catalytic partial oxidation reformer for forward operating bases

A forward operating base tends to have limited access to a power grid in addition to unique operating constraints. In order to meet its power requirements, a system that is compact and easy to operate is desirable. A catalytic partial oxidation (CPOX) reformer coupled with a generator offers compactness and ease of operation along with fuel flexibility. A 1 kW CPOX system was tested as part of a microgrid based on the Missouri University of Science and Technology microgrid. The system was made to follow a number of input current waveforms to simulate real-world loads using a programmable DC load. The system was demonstrated good load-following capabilities with the maximum average deviation for any given test not exceeding 30.1 W. This deviation increased as the power demand increased. The performance of the generator was found to be independent of the sulfur content of the fuel. The overall efficiency of the system was found to be 5-10%. Deposition of coke and unsteadiness in the generator were found to be issues. Solutions were proposed.
