Researchers at the University of Science and Technology of China (Hefei, China) demonstrated the efficient production of hydrogen from bio-oil via an electrochemical catalytic reforming method over a CoZnAl catalyst.
A paper on their work appears in the Chinese Journal of Chemical Physics.
Both the hydrogen yield and carbon conversion were “remarkably” enhanced by the current through the catalyst, reaching hydrogen yield of 70% and carbon conversion of 85% at a lower reforming temperature of 500 °C.
The researchers also characterized the influence of current on the properties of the CoZnAl catalyst by X-ray diffraction, X-ray photoelectron spectroscopy, thermal gravimetric analysis, and Brunauer-Emmett-Teller measurements. Thermal electrons play an important role in promoting the reforming reactions of the oxygenated-organic compounds in the bio-oil.
