Preparation of porous carbons from petroleum coke by …
This means that under identical preparation conditions, the yield of porous carbons for the MPC coke would be higher than that for the SPC coke, and this can be easily seen from Table 3. In addition to the organic constituents, the inorganic components in petroleum cokes are also important factors that cannot be neglected or underestimated.
