A process simulation of the NEDOL coal liquefaction process

A coal liquefaction pilot plant of the NEDOL process, supported by the New Energy and Industrial Technology Development Organization (NEDO), was in su ccessful operation for a total of 269 days at Kashima, Japan. The liquefact ion section consisted of three reactors, 1 m in diameter, connected in seri es, and processed 150 tons of coal per day. Product yields were modeled ass uming 13 reaction paths, and a steady-state simulator was developed. The pe rformance of the entire process, including distillation and solvent hydroge nation sections, was further incorporated into the simulation. The design p rocedure for the liquefaction reactors, which would possess a diameter of 4 m and process 2500 tons of coal per day, was discussed in sight of the sim ulator.
