Claim:
1. A method for the conversion of asphaltenes to light fractions, comprising: a process of reacting a hydrogen donor solvent with an asphaltene-containing feedstock, and reaction products are subsequently fractionated, wherein a weight ratio of the hydrogen donor solvent to the asphaltene-containing feedstock is 0.1-5:1, a weight hourly space velocity of the reaction is 0.2-5 h −1 , reaction pressure is 0.5-25 MPa, reaction temperature is 360-500° C., and the hydrogen donor solvent is a solvent containing polycyclic aromatic compound having α-hydrogen; and the method further comprising introducing hydrogen to a reactant comprising the asphaltene-containing feedstock and the hydrogen donor solvent, wherein a volume ratio of the introduced hydrogen to the reactant comprising the hydrogen donor solvent and the asphaltene-containing feedstock is 10-1000:1.
