Note:Reaction conditions covered a poplar powder of 10.0 g，a methanol dosage of 80.0 g，a soybean oil amount of 50.0 g（when it was applied in the reaction），and a reaction time of 1.0 h.

The poplar powder used in the experiments was P1，with the results presented in Table 2.Similar to BFAME，soybean oil could also promote the liquefaction and decomposition of poplar powder in supercritical methanol，and the average increase in the decomposition rate was around 15%，which was higher than that achieved by BFAME，although the reaction conditions were not completely the same.The reasons are still not thoroughly studied，but there were possibly two factors that could affect the difference，namely:1) the viscosity of soybean oil was higher than that of BFAME，which might improve the dispersion of poplar powder in supercritical methanol and promote the liquefaction and decomposition；2) glycerol was produced when soybean oil was used[16]，which might become a kind of liquefaction solvent and could promote the liquefaction and decomposition reaction.
