摘要：
Solvent extraction offers a simple but generally ineffective approach to the desulphurization of high-sulphur petroleum coke where the organic sulphur compounds present may be selectively dissolved. Pre-oxidation of petroleum coke at a moderate temperature (600 K) renders the coke more amenable to the solvent extraction treatment. The desulphurization efficiency was greatly improved when pre-oxidized coke samples were extracted using different solvents. A maximum desulphurization of 76% was achieved.
