Abstract:
Highly effective production of hydrogen from bio-oil was achieved by using a low-temperature electrochemical catalytic reforming approach over the conventional Ni-based reforming cat- alyst (NiO-Al2O3), where an AC electronic current passed through the catalyst bed. The promoting effects of current on the bio-oil reforming were studied. It was found that the performance of the bio-oil reforming was remarkably enhanced by the current which passed through the catalyst. The effects of currents on the microcosmic properties of the catalyst, including the Brunauer-Emmett-Teller (BET) surface area, pore diameter, pore volume, the size of the crystallites and the reduction level of NiO into Ni, were carefully characterized by BET, X-ray diffraction, X-ray photoelectron spectroscopy, and scanning electron microscope. The desorption of the thermal electrons from the electrified catalyst was directly observed by the TOF (time of flight) measurements. The mechanism of the electrochemical catalytic reforming of bio-oil is discussed based on the above investigation.

摘要:
通过低温电催化重整方法(电流通过催化剂床),用传统的镍基重整催化剂NiO-Al2O3重整生物油制取氢气是一种高效的生物油产氢方法.还探索了电流对生物油重整的促进影响,发现通过催化剂的电流明显地提高了生物油的重整.通过BET、XRD、XPS和SEM的测试,研究了电流对催化剂微观结构的影响,包括比表面、孔径、孔体积、晶粒尺寸和氧化镍的还原程度.从通电的催化剂表面脱附的热电子直接由飞行时间质谱测量.讨论了电催化重整生物油的机理.
