In order to improve the utilization rate and added value of wood packaging waste and broaden the application field of wood resources, the influence of liquid-solid ratio, catalyst content, liquefaction temperature, and reaction time on lignocelluloses liquefaction product was studied. The result showed that with the raise of liquefaction temperature, the residual rate raises first and than drops with minimum value at 160 ℃; along with the catalyst content's raise, the rate of liquefaction of cellulosic residues is on the decline, which is more evident when the catalyst content drops below 6%; when the liquid solid ratio is less than 5∶1, the residual rate decreases obviously; the contribution of increasing reaction time to the residual rate reduces gradually.
