Study on Catalytic Properties of Mesoporous La 0 . 6 Pr 0 . 4 BO 3 Composite Oxide in the High-Pressure Liquefaction of Bagasse

Cationic surfactant CTAB as organic template agent mesoporous, La0.6Pr0.4BO3 (B = Mn2+, Cu2+, Co2+, Fe3+, Ni2+) perovskite-type oxide were synthesized by co-precipitation method. The crystalline structures, surface topography, superficial area, pore size distribution and surface properties were characterized by XRD, FI-IR, BET and temperature programmed technology; at the same time, the catalytic performances of B-site ions replaced of mesoporous La0.6Pr0.4BO3 perovskite and liquefaction product distributions and yield of liquefied oil in the process were studied. The results showed that Mn2+ ions replaced of mesoporous La0.6Pr0.4MnO3 characteristic diffraction peaks relatively stronger, higher degree of crystallinity of the sample, preferably channel, having a larger specific surface area, is 21.98 m2·g−1 and the most probable pore size is 32.27 nm and stronger surface conductivity and oxygen species alkaline center, the yield of liquefied oil is 59.68% and rate of residue is 12.62% on bagasse high-pressure liquefaction reaction. At the same time, the main components of liquefied products are p-ethyl phenol, phenol, p-benzyl alcohol and o-guaiacol.
