Carbon fibers and process for their production, and fiber-reinforced

Disclosed herein are a process for producing needle coke, which comprises reducing the ash content in a heavy oil obtained from fluid catalytic cracking of petroleum or in a hydrocarbon material mainly composed of said heavy oil to not more than 0.01 wt % by means of (1) filtration, (2) centrifugation, (3) electrostatic aggregation or (4) a combination thereof, and coking the thus treated heavy oil or hydrocarbon material with an ash content of not more than 0.01 wt %; and a needle coke produced by coking a heavy oil obtained from fluid catalytic cracking of petroleum or a hydrocarbon material mainly composed of said heavy oil.
