Abstract

Pyrolysis experiments of isobutane, isobutylene, and 1-butene were performed over a temperature range of 550-750 ^oC and a pressure of ~ 0.8 atm. The residence time was ~ 5 s. The fuel conversion and product selectivity were analyzed at these temperatures. The pyrolysis experiments were performed to simulate the gas phase chemistry that occurs in the anode channel of a solid-oxide fuel cell. The experimental results confirm that molecular structure has a substantial impact on pyrolysis kinetics. The experimental data show considerable amounts of C₅ and higher species (~2.8 mole % with isobutane at 750 ^oC, ~7.5 mole % with isobutylene at 737.5 ^oC, and ~7.4 mole % with 1-butene at 700 ^oC). The C₅+ species are likely deposit precursors. The results confirm that hydrocarbon gas phase kinetics have substantial impact on SOFC operation.
