随着世界原油品种的变重和对轻油需求的增加,重油改质变得日益严重,但是大部分改质工艺总有在加氢处理时的生焦问题.生焦将使催化剂变坏,反应器、炉子、换热器和其它设备的压降增高并使产品的稳定性降低.三位日本研究人员根据煤液化和重油改质中,使用有供氢能力的氢化芳烃如四氢萘 As the world’s crude oil variety becomes heavier and the demand for light oil increases, heavy oil upgrading becomes more and more serious, however, most of the upgrading processes have a green cokemaking problem at the time of hydrotreating. Coke coke will deteriorate the catalyst, Increases in the pressure drop of furnaces, heat exchangers and other equipment and decreases the stability of the product.Three Japanese researchers in accordance with the coal liquefaction and heavy oil upgrading, the use of hydrogenated aromatic hydrocarbons such as tetrahydronaphthalene
