1. a kind of method that visbreaker tar refines standby liquid fuel with coal altogether, comprises the following steps:

  • (1) heavy oil at 400~500 DEG C, heating be no more than 30min, carry out thermal cracking visbreaking process, obtain visbreaking product;

    (2) the visbreaking product in above-mentioned steps (1) is separated, obtains gaseous substance and liquid phase substance;

    (3) solvent naphtha is added in the liquid phase substance into above-mentioned steps (2) to be well mixed, obtain mixed solvent;

    (4) mixed solvent in the step (3), coal dust and catalyst are mixed, preparation obtains coal, with butt coal dust matterGauge, the ratio of the addition of the mixed solution, coal dust and catalyst is (50~70):

    (50;

    ~30):

    (0.2~5);

    (5) the hydrogenated reaction of the coal obtains liquid fuel;

    Wherein 250~500 DEG C of cut is recycled in liquid fuelThe step (3) uses as solvent naphtha.
