【摘要】 基于对稠油水热裂解反应机理的分析,讨论了供氢体改质稠油的机理,综述了国内外利用供氢体对稠油进行改质研究的思路及其进展,介绍了无机、有机供氢体,并对其优缺点进行了评述。指出了高芳烃重质石油馏分及异丙醇等醇类作为经济型供氢体的可行性。稠油井下水热裂解改质技术的关键之一是寻找供氢效果更好、来源广泛、适宜的工业用供氢体。表1参42。更多还原

【Abstract】 The mechanisms involved in catalytically upgrading heavy crude oil(HCO) by aquathermolysis(ATh) using hydrogen donor are presented on the basis of a mechanistic analysis of ATh of HCO;the concepts and researches on upgrading HCO using hydrogen donor performed at home and abroad are summarized;the hydrogen donors of inorgainic and organic classes,prepared or developed and used,are reviewed with their advantages and disadvantages stated.The feasibility of using highly aromatic hydrocarbon fractions of HCO and alcohols such as isopropanol as cheaper hydrogen donors is demonstrated.One of the key problems to solve in the technology of downhole upgrading HCO using hydrogen donor is to develop more effective,commercially available and suitable for field uses hydrogen donors.更多还原
