Abstract: Aiming at the technical and economic problems in hydroprocessing technologies for different coking fractions, FRIPP has developed a combination process of hydrocracking - hydrotreating, which is characterized by simple process, high integration and sharing of equipment, less units, good quality of products, and low cost of investment and operation. Feedstock adaptability test results show that this technology has very good feedstock adaptability and high operating flexibility. High quality naphtha and ultra-low sulfur diesel can be obtained when processing coker fractions with high content of nitrogen or high end boiling point under mild operating conditions.
