Abstract: With the global regulations restricting the sulfur content of marine fuel, low-sulfur marine fuel has become a reliable path for the shipping industry to achieve sustainable development. It is particularly important to develop new components to improve the economy and production capacity of low-sulfur marine fuel. Based on the catalytic cracking technology (MFP) that produces propylene and marine fuel components, a detailed analysis was conducted on the properties of the MFP marine fuel components. Then, taking into account the actual production of refinery, research has been conducted on the blending of MFP marine fuel components to produce new low-sulfur marine fuel products. Finally, the low-sulfur marine fuel product produced through formula optimization meets the RMG380 standard and has good stability. The MFP marine fuel components have expanded the optional range of low-sulfur marine fuel components, providing technical support for improving the production capacity and efficiency of low-sulfur marine fuel in China.

Key words: catalytic cracking, marine fuel and propylene(MFP), technology, blending, low sulfur marine fuel
