1. the method for preparing rice bran porous active Carbon Materials, the method comprises:

  • Step 1;

    dry to moisture content as being less than 14% under field conditions (factors) or 10 ℃



    220 ℃

    of wooden chaffs;

    Step 2;

    by 250 ℃



    1500 ℃

    carbonizations under protection of inert gas of dried rice bran.The one, in microwave device, microwave radiation under the power of 700~

    1500W, 2~

    40 minutes, the one, in carbide furnace, activate 20~

    400 minutes;

    Step 3;

    the rice bran after carbonization and different mass activator mix, then 300~

    1200 ℃

    of activation under protection of inert gas, the one, in microwave device, microwave radiation under the power of 700~

    1500W, 2~

    40 minutes, the one, in activation furnace, activate 20~

    500 minutes;

    Step 4;

    be 6.5~

    7 rear being dried with adding distil water filtering and washing to pH value, prepare porous activated carbon.
