| description | Activated coke was obtained by CO2 activation with disused fine blue-coke serving as the main raw material and direct coal liquefaction residue (DCLR) as binder. The effect of the dosage and activation temperature of DCLR on the compressive strength of active coke and desulfurization were mainly investigated. The experimental results showed that the compressive strength of the activated coke increased first and then decreased with the increase in the amount of D-DCLR (DCLR after ash removal). When the amount of D-DCLR was 40%, the compressive strength of the activated coke was 492.55 N and the specific surface area was the highest (189.78 m2·g−1) among other samples. The results show that the activated coke has a high removal rate for low concentrations of sulfur dioxide. This work provides a way for efficient utilization of DCLR, which avoids waste of resources and environmental pollution. In addition, it is important for finding green and efficient blue-coke powder processing and utilization technology for the sustainable development of the blue-coke industry. |
