Research into hydro-liquefaction of bamboo based on GPC

We investigated hydrogenated catalytic liquefaction of bamboo. By comparing the effect of three kinds of conditions on liquefaction, i.e. liquefaction under vapor pressure, liquefaction under high hydrogen pressure and liquefaction under high hydrogen pressure with alkaline as a catalyst, we obtained the conditions for optimum results. The reaction temperature was 170℃, the initial hydrogen pressure 4.0 MPa, the reaction time 80 min, with sodium hydroxide as the catalyst, with a weight amounting to 8.05% of that of dried bamboo. Under these optimum conditions, the yield of the liquid was 58.55% and the conversion ratio of polysaccharides 70.62%.
