 Promoting the conversion of poplar to bio-oil based on the synergistic effect of alkaline hydrogen peroxideHaijun Wu, Xinlong Li, Quan Zhang, Kai Zhang, Xia Xu and Jian Xu Renewable Energy, 2022, vol. 192, issue C, 107-117 Abstract: The synergistic catalysis effect of NaOH and H2O2 on the hydrothermal liquefaction (HTL) of poplar was investigated and compared to the NaOH or H2O2 catalyzed HTL at different temperatures and 30 min residence time. GC-MS, GPC, FT-IR, HPLC and TGA were used to comprehensively characterize the physical and chemical properties of liquefied products (bio-oil, lignin and solid residue). The results showed that the highest total bio-oil yield (70.65%) was obtained at 280 °C with NaOH (35 g/L)/H2O2 (30 g/L) as catalysts. The average molecular weight and polydispersity index (PDI) were found to be lower compared to that from other conditions. As the NaOH concentration was increased, the bio-oil yield was improved. The concentration of H2O2 for the optimal synergistic effect was observed to be 30 g/L. GC-MS analysis showed that the bio-oil obtained by NaOH (35 g/L)/H2O2 (30 g/L) was characterized with the lowest N content. The synergistic effect promoted the higher production selectivity of o-xylene and p-xylene in the bio-oil.
