  The present disclosure provides a method for separating soluble organic matter in petroleum coke, including: drying the petroleum coke to obtain pretreated petroleum coke; extracting the pretreated petroleum coke sequentially with petroleum ether, carbon disulfide, ethanol, acetone-carbon disulfide mixture and tetrahydrofuran to obtain an extract and the treated petroleum coke, wherein the extract includes soluble organic matter. The method provided by the present disclosure employs extractants with different polarities, i.e., petroleum ether, carbon disulfide, ethanol, acetone-carbon disulfide mixture and tetrahydrofuran, to extract petroleum coke sequentially, so as to detect the composition of the soluble organic matter in petroleum coke at the molecular level, realizing the separation of soluble organic matter in petroleum coke at the macro molecular level, as well as the determination of molecular structure of soluble organic matter in petroleum coke by modern detection processes.
