the invention provides an integrated process for processing heavy oil , wherein the integrated process at least comprises : solvent deasphalting is carried out for heavy oil material , and de - oiled asphalt phase is mixed with dispersing agent and then entered a thermal cracking reactor to undergo thermal cracking reactions . upgraded oil can be obtained through the mixture of the de - asphalted oil and thermal cracking oil separated from thermal cracking reaction products . the solvent and heavy gas oil , which are separated from the thermal cracking reaction products , are respectively recycled back to the solvent deasphalting process as solvent and as mixed feed to remove asphaltene . the integrated process of the present invention solves the problems that solvent is difficult to be separated from asphalt with high softening point in solvent deasphalting process and hard asphalt is difficult to be transported .
