Experimental study on the direct liquefaction of Cunninghamia lanceolata in water


  • Qu, Yixin
  • Wei, Xiaomin
  • Zhong, Chongli


Direct liquefaction of Cunninghamia lanceolata in water was carried out in an autoclave in the reaction temperature and time ranges of 280–360° C and 10–30 min, respectively, and three feedstock ratios of biomass/water were tested. The experimental results show that the yield of heavy oil has a maximum between 320 and 340° C, depending on the reaction time and the feedstock ratio adopted. At the experimental conditions of this work, the maximum heavy oil yield is about 24%, obtained at the feedstock of 8 g biomass and 100 ml distilled water, with the reaction time of 10 min and the reaction temperature of 320° C.
