Embodiment 1
[0039] use as figure 1 The shown oxidative carbonization device performs oxidative carbonization treatment on the shaped pellets of raw coal, wherein the internal structure of the first cylinder is as follows figure 2 Shown; the second cylinder is provided with a copy board with the same structure. In addition, the first outer heating jacket and the second outer heating jacket are each provided with 6 segmented jackets.
[0040] The briquette is crushed and granulated to obtain granules with a particle diameter between 6.7 mm and 8 mm. During the oxidation treatment, the inner temperature of the cylinder corresponding to the first segmented jacket of the first external heating jacket is controlled to be 150-170°C, and the temperature inside the cylinder corresponding to the sixth segmented jacket is 200-220°C, during which the temperature rise rate is 0.2~0.5°C / min; use air as the oxidant to oxidize for 2.5 hours to obtain the oxidized material.
[0041] Then send the oxid...
