Abstract
The present invention provides a method for the conversion of asphaltenes to light fractions, including: a process of reacting a hydrogen donor solvent with an asphaltene-containing feedstock, and fractionating reaction products, where 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, 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. The method according to the present invention can effectively achieve light fraction conversion of the asphaltenes to light fractions, and the process operation is simple.
