Porous carbon material and the manufacturing method making the same

The invention discloses a porous carbon material and a manufacturing method thereof. The manufacturing method of the porous carbon material comprises the following steps of: step (1) performing a pre-treatment of an organic waste; step (2) performing a thermal cracking process on the organic waste after the pre-treatment under a first oxygen-less condition to collect a solid substance and a liquid substance during the first thermal cracking process; step (3) mixing the solid substance and the liquid substance to form a mixed sticky substance and step (4), performing a microwave pyrolysis process on the mixed sticky substance under a second oxygen-less condition with a heating rate larger than 50 DEG C/min) to heat mixed sticky substance at a temperature between 500-800DEG. The porous carbon material has a lower cost and a larger specific surface area, and its manufacturing method is simple and convenient to operate, and quickly saves energy.
