Development trends of catalytic cracking
Thread Content
What is the future development direction of catalytic cracking? As a person in the refining and petrochemical industry,
Simple heavy oil cracking has a significant impact on the catalytic processing capacity and product distribution; as the feedstock becomes heavier, it is recommended to pre-hydrogenate the catalytic feedstock before feeding it into the catalyst. Based on current trends, it seems that there is limited room for development in using catalytic cracking to produce petroleum products; it is recommended to opt for catalytic pyrolysis and pursue a chemical processing approach instead.
Hydrogenation of residue oil, and hydrogenation of wax oil before feeding it into catalytic cracking; simple catalytic cracking of heavy oil is now used very rarely
In our unit, paraffinic oil and residue are first subjected to hydrogenation before being sent for catalytic cracking

Catalytic cracking has been developed for over 100 years, so its maturity is evident; in particular, China has reached an internationally leading level, leaving little room for further development. Consider factors such as the advancement of supporting facilities, atomization efficiency, rapid separation technology, deep cracking, high olefin production, and high octane number as well as high cetane number. Pre-treatment of relevant raw materials, development in terms of higher added value for products, etc. Thank you!
The raw materials are becoming heavier, the requirements are increasing, the ratio of wood to gas is gradually decreasing, and the efficient utilization of light components is receiving more attention
