Preparing porous carbon from petroleum coke is one of efficient strategies to make petroleum coke value-added.2 However, petroleum coke is rich of benzene rings or aromatic domains and has dense structure, resulting in difficulties in activation. Up to date, chemical activation with KOH is still a primary means1–12 to activate petroleum coke.

Feb 03, 2021· The theoretical amount is about 2% higher. Artificial graphite powder and petroleum coke each account for 50% of the total carbon added amount, and then 3%-4% higher than the theoretical amount. Mix the prepared three raw materials in a ball mill and add them to the arc B4C can be obtained by reducing and carbonizing the furnace at 1700-2300℃.
Figure 5 shows cross-sectional carbon-mapping images of the ZSM-5 particle after the reaction time of 3, 6, and 12 h. As the reaction proceeds, it can be seen that coke is produced more along the edges of the crystal than in its interior. Thus, the coke does not exist in the interior of the pores, but mainly on the outer surface or near the pore
