Design characteristics and operating performance evaluation, for a multichannel reactor approximately 4.5” X 0.5” X 1.0” in size, is discussed. Temperature, throughput, and mode of operation are variables explored. Two modes of operation were investigated: 1) under adiabatic conditions and 2) utilizing counter-current air cooling. The latter scenario offered a differential temperature profile which helped to improve performance. Demonstration of this concept is provided. Maintaining the inlet reactor temperature at 430 C the methane effluent composition output increased from 66.2% to 79.9% by introducing counter-flow air cooling. This allowed the exiting reactor temperature to decrease by ~ 100oC.
