The invention relates to deep processing technology of coal-tar asphalt, in particular to the process for co-production of high-quality carbon black raw oil, refined asphalt and binder asphalt. The process comprises a step of mixing crude coal-tar asphalt and a solvent in a certain ratio and injecting the mixture into an extraction separator for separating, wherein the process comprises technicalsteps: mixing the crude coal-tar asphalt and the solvent in a certain ratio and injecting the mixture into the extraction separator and performing extraction, flocculation, sedimentation and separation; extracting a light phase component, a secondary light phase component and a heavy phase component from an upper position, a middle position and a lower position of the separator respectively according to a density distribution principle; and controlling the ratio between double solvents and the ratio between the double solvent and the crude coal-tar asphalt, wherein the double solvents consistof an aromatic solvent and an aliphatic solvent. The process not only can obtain the high-quality carbon black raw oil with a high additional value and prepare pure refined asphalt and carbon for needle coke and the binder asphalt for a refractory material product, and but also has no waste emitted in the overall technical process.
