Interconnected porous carbons were successfully synthesized via a facile one-step method from abundant and low-cost coal tar pitch (CTP) and microcrystalline cellulose (MCC) for high-performance supercapacitors. The as-prepared IPCs possess unique interconnected porous networks and large surface area (up to 3305 m2 g−1), which could mainly be ascribed to the combined effects of template effect from...
A technique for the removal of quinoline insolubles (QI) and ash in coal tar pitch (CTP) using a high-voltage electrostatic field (EF) was developed. QI and ash removal were carried out under an electrical field strength of 2.25×10 5 V/m and a temperature of 35°C with oil washing as the solvent. The results showed that QI and ash can be deposited onto cathodes under optimal conditions. CTP...
A procedure for the desulfurization of coal tar pitch (CTP) by oxidation with hydrogen peroxide (H 2 O 2 ) was developed, in which trichloroacetic acid (TCA) was used as a catalyst combined with ultrasonic waves. For comparison, the effects of H 2 O 2 combined with different catalysts on sulfur removal were also investigated. The oxidative system composed of H 2...
