  • Publication number: 20170356015
    Abstract: A method for pretreating a wood dust includes conducting a structurally damaged step and an alkali treatment step. In the structurally damaged step, the wood dust is disposed in a scCO2 atmosphere with a pressure of 2600 psi to 3400 psi at a temperature of 40° C. to 120° C. for a predetermined time, and then the pressure is adjusted to drop to an atmospheric pressure in a sudden manner to obtain a structurally damaged wood dust. In the alkali treatment step, the structurally damaged wood dust is immersed in an alkaline H2O2 solution at a temperature of 50° C. to 70° C., a concentration of H2O2 in the alkaline hydrogen peroxide solution is in a range of 0.1 wt % to 2.1 wt %, and a pH value of the alkaline H2O2 solution is in a range of 10.5 to 12. Thus a treated wood dust is obtained.
