Preparation and application of a new catalyst to produce bio-oil from microalgae liquefaction

Wang Yipeng, Nan Ge, Wang Wenjia, Zhang Jinglai, Han Wei


In this study, hydrothermal catalytic liquefaction method was adopted to produce bio-oil from microalgae. The influence of supported Ni-Catalysts doped neodymium (Nd) on the bio-oil yield from microalgae liquefaction was investigated, aiming to find the optimal preparation procedure of bio-oil. It proved that under the condition of a temperature of 270°C and a reaction period of 30 min, the bio-oil yield of hydrothermal catalytic liquefaction of spirulina powder could reach 55.1% by means of the catalyst prepared with 1 mol/L neodymium nitrate as the dipping solution after a calcination for 4 h at 800°C. In addition, the characterization on catalyst was discussed in this research.
