The invention discloses a method for preparing asphalt-base carbon fiber by taking coal directly liquefied residues as a raw material. The method comprises the following steps that: mixed solution of coal directly liquefied residue powder and tetrahydroquinoline solvent is filled into a high pressure autoclave, and is heated to a temperature of between 150 and 400 DEG C after air in the autoclave is replaced by nitrogen; hydrogen is introduced into the autoclave while pressure is increased to 2 to 50MPa; most elements, such as sulfur, oxygen, nitrogen and the like, contained in original residues are removed through distilling under reduced pressure; removing tetrahydroquinoline insoluble substance through filtering under reduced pressure, reclaiming the tetrahydroquinoline solvent through distilling under reduced pressure, and recycling the tetrahydroquinoline solvent; and the obtained tetrahydroquinoline soluble substance can be produced into the asphalt-base carbon fiber through melt spinning, pre-oxidation, low temperature carbonization, high temperature carbonization, superficial treatment, post treatment and other processes.
