Process for preparing fuel oil by using coal tar

This invention relates to a process for producing fuel oil from coal oil, comprising: 1. vacuum dehydrate the coal oil; 2. distill the dehydrated coal oil to produce =360Deg C fraction; (1) dephenolize and denaphthalenize the =360Deg C fraction to produce the <=360Deg C fraction, then add hydrogen for refining and modification, and lastly distill to produce superior benzin naphtha and diesel fuel fractions. The invention is characterized of broad range of raw material, rational process, easy industrial production, and flexible operation.
