This article presents the results from the primary treatment of heavy crude oil in the presence of activated carbon and a supercritical aqueous fluid. This makes it possible to reduce the content of sulfur and resinous-asphaltene substances significantly and to increase the amount of light fuel fractions. The work revealed distinctive features of the change in composition and properties of the liquid products of the conversion of crude oil in a hydrothermal fluid at 420°C and also in the presence of activated carbon at the process temperature 375°C. The possibility of reducing the conversion temperature of crude oil due to the presence of active carbon in the reaction medium is demonstrated. It was established that light fractions are formed in the transformed heavy crude oil in a hydrothermal fluid in the presence of activated carbon due to destruction of the resin-asphaltene components. The technology is aimed at environmentally safe and residue-free processing of heavy hydrocarbon resources to obtain high-quality raw materials rich in fuel fractions.

本文介绍了在活性炭和超临界水性流体存在下对重质原油进行初级处理的结果。这使得可以显着降低硫和树脂沥青质物质的含量并增加轻燃料馏分的量。该工作揭示了原油在 420°C 的热液流体中以及在 375°C 的工艺温度下在活性炭存在下转化的液体产物的组成和性质变化的显着特征。证明了由于反应介质中存在活性炭而降低原油转化温度的可能性。已经确定，由于树脂-沥青质组分的破坏，在活性炭存在下，在热液流体中转化的重质原油中形成轻馏分。该技术旨在对重烃资源进行环境安全和无残留加工，以获得富含燃料馏分的优质原材料。
