Abstract: 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.

Abstract translation: 本发明提供了一种加工重油的综合方法，其中一体化方法至少包括：对重油材料进行溶剂脱沥青，脱油沥青相与分散剂混合，然后进入热裂解反应器进行热处理 开裂反应。 通过从热裂解反应产物中分离的脱沥青油和热裂解油的混合物可以获得升级的油。 与热裂解反应产物分离的溶剂和重质瓦斯油分别作为溶剂和混合进料循环回到溶剂脱沥青法中以除去沥青质。 本发明的一体化方法解决了在溶剂脱沥青工艺中溶剂难以与高软化点的沥青分离的困难，难以运输硬沥青的问题。
