Abstract
Catalytic pyrolysis of distillers dried grain with solubles by nickel-based catalysts was performed. The effects of pyrolysis temperature, catalytic carrier and components on the products were investigated. The catalysts were characterized with NH3-TPD, XPS, H2-TPR. The average higher heating value (HHV) of the bio-oil was about 61% of the HHV of gasoline. GC/MS analysis indicated that the bio-oil contained some value-added compounds such as 2-furaldehyde, 2-furanmethanol, 3-pyridinol, dodecane, etc. The pyrolysis gas rich in hydrogen was obtained under the direct catalysis of nickel-based catalysts. For Ni–Pd-γ-Al2O3, the volume percentage of hydrogen in gas reached 55.6 vol.% at 500 °C, revealing that there was a strong synergistic effect between Ni and Pd. According to the experimental results the possible mechanism was proposed. It was considered that the metal species over catalyst was the most important factor for its performance, and the influence from its Lewis acidity could not be ignored.
