Abstract:

The catalytic cracking diesel upgrading unit has high design pressure, high catalyst activity and large product adjustment range, originally designed to produce hydrogenated diesel components that meet the requirements of the catalytic cracking unit of the LTAG unit. By accounting for the unit and adding a small number of processes, the processes for producing low sulfur marine fuel oil and vehicle diesel have been added. By adjusting the feedstock and the operating parameters of reaction system of the unit and adding a small amount of additives, qualified low sulfur light marine fuel and vehicle diesel products are produced. The function of the device has been greatly improved, increase the ability of enterprise to produce low sulfur marine fuel and vehicle diesel. On the basis of maintaining the advantages of product oil production, it has moved towards the direction of special oil products, which has enhanced the competitiveness of the enterprise.
