The maximum yield of Summerwood bio-oil was 63.8%,which was achieved at 500℃ and feed rate 20.14kg/h with a particle size 0.47~0.67mm.

其中，楸木木屑在反应温度为500℃、粒径为0.47～0.67mm、给料速率为20.14kg/h的条件下产油率达到最高值。

The DFT (B3LYP/6-31 + G) method was used to study the relative stabilities and probable proton transfer in isolated and monohydrated 2,4-dithiothymine molecules in gas phase. The effects of water on relative stabilities and the rate of the proton transfer were analysed. The results indicate that only one tautomer for 2,4-dithiothymine can exist in gas phase.
