Suspended Bed Hydrocracking - Direct Deep And Efficient Conversion Technology Of Inferior Heavy Oil

According to the four major challenges and problems faced by the oil refining industry,we will introduce the best technology for direct deep and efficient conversion of inferior heavy oil—suspended bed hydrocracking technology, including development history and comparison with fixed bed and ebullating bed hydrogenation technology.It analyzes the current situation and development trend of suspended bed hydrocracking catalysts and processes, and introduces the suspended bed hydrogenation technology under construction and ready for industrialization. Foreign suspended bed hydrogenation technologies include EST technology of Italian Eni company, VCC technology of American KBR company, Uniflex suspension bed residue hydrogenation technology of UOP company, HDHPLUS technology of Venezuelan state oil company (PDVSA), VRSH technology of CHEVRON company.In China, there is a suspended bed hydrogenation technology jointly developed by PetroChina and China University of Petroleum (East China).The technical and economic comparison of four heavy oil conversion technologies including suspended bed, fixed bed, delayed coking and heavy oil catalysis.It is pointed out that domestic catalysts, feedstock properties, transformation mechanisms and reaction engineering should be carefully studied, and through joint ventures, independent development, etc.,Strive to keep pace with the world or be in the forefront of the world in suspension bed hydrocracking technology through 5-10 years of hard work.
