Petroleum Catalytic Cracking

Catalytic cracking FCC is a traditional refining process, the main products are gasoline, diesel and other fuel oil products, propylene as a by-product, the yield is low.To improve propylene yield,

UOP's PetroFCC process and RxPro process, Sinopec Petrochemical Research Institute's Deep Catalytic Cracking (DCC), Nippon Oil Corporation and Saudi Aramco's

High Severity Catalytic Cracking (HS-FCC) technology Such processes have been gradually developed, 

and the yield of propylene produced from VGO (heavy components such as vacuum diesel) as raw materials can reach levels of over 20%, 15-25%, and close to 20%, respectively.
