Abstract

A process for producing pitch for the production of carbon fibers, which process comprises subjecting a heavy oil obtained in fluid catalytic cracking of petroleum and having a boiling point not lower than 200°C, to the action of a high gradient magnetic separator to capture and remove fine particles contained in the heavy oil, and then heat-treating the heavy oil at a temperature in the range of 380° to 480°C and a pressure in the range of 2 to 50 kg/cm²·G.
