A high-purity hydrogen fed to the fuel cell system makes waste Motor oils (MOs) utilization system economically and environmentally attractive. Thus, the main objectives of this work were to develop a MOs catalytic reforming process and the potential applications of hydrogen from syngas (CO and H2) on fuel cells. A NiO- or CuO/zeolite was also further identified by FE-SEM/EDS, XPS, EPR or XANES/EXAFS. Experimentally, MOs catalytic reforming was accompanied by a substantial production of syngas at 760-900 K. It was found that in addition to over 92% of syngas generation, approximately 8.35×105 kcal/h of thermal energy was recovered and the cold gas efficiency was 79-88% when the reformer was operated at O/C atomic ratios of 1.1-1.3. The product syngas can be separated by pressure swing adsorption and Pd membrane purification units, which effectively purified and generated 99.999% pure hydrogen in an integrated FC processor. Finally, cost or benefit analysis of MOs reformer of 10- or 20-TPD (tons per day) was also performed to confirm the economic potential for such a recycling practice and determine if further development of stationary FC system would be warranted.
