Abstract: To meet the needs of market product structure adjustment and the transformation and upgrading of refineries, based on the research and development of S-RHT fixed bed residue hydrotreating technology in the early stage, a new catalyst system and process technology have been adopted to develop fixed bed residue hydrotreating technologies with different characteristics. By using shallow hydrotreating catalysts, grading systems, and their process technologies, low sulfur marine fuel with sulfur mass content less than 0.5% and sediment that meets the requirements can be directly produced. According to the different properties and characteristics of residue feedstock, two types of combined technologies for producing low sulfur petroleum coke have been developed, which can produce petroleum coke meeting the standards of 3B and 2A, respectively. Hydrogenated heavy oil obtained by using the deep fixed bed residue hydrotreating technology has a hydrogen mass content greater than 12.5%, which is a high-quality feedstock for downstream catalytic cracking units.
