Abstract: The present situation of refining industry in China and the challenges faced under the new situation were analyzed, and the necessity of transformation and development was elaborated. The development and application of clean transportation fuel production, low-cost production of basic organic chemical raw materials, high-value special chemicals production and carbon dioxide emission reduction technology are key to support the transformation and development of refining industry. The experimental and practical application of new technologies such as solid acid C4 alkylation for high-octane-gasoline production, biojet fuel production, diesel ultra-deep hydrodesulfurization (RTS), production of low sulfur marine fuel oil, adsorptive separation of n-alkanes from full fraction naphtha, combination of directional hydrotreating with selective deep catalytic cracking (DCC) process for maximum propylene (SHMP), residue to chemicals (RTC) process, light cycle oil (LCO) to aromatics and gasoline (LTAG) process, RHT-DCC bi-directional combined process for producing chemical raw materials from residual oil (RICP), high end needle coke production, low viscosity poly-α-olefins (PAO) production, integration of fluid catalytic cracking (FCC) gas oil hydrotreating and highly selective catalytic cracking for maximizing liquid yield (IHCC), low energy consumption continuous diesel liquid-phase hydrotreating (SLHTDR) process, were introduced.

Key words: catalytic cracking, hydrodesulphurization, jet fuel, marine fuel oil, needle coke, poly-α-olefin, propylene, decarbonization
