1. Improve the quality and added value of petrochemical products Petrochemical catalysts can improve the performance of petrochemical products and enhance their quality and added value. For example, the use of catalytic cracking technology can convert heavy crude oil into light gasoline, diesel and other high-value products, which improves the utilization rate and economic benefits of crude oil. The use of catalytic reforming technology can improve the octane number of gasoline, increase its knock resistance, reduce automobile exhaust emissions, and protect the environment. The use of catalytic hydrogenation technology can remove sulfur, nitrogen and other impurities in petroleum products, reducing the corrosion and pollution to the equipment.

2. Save petrochemical resources and energy The petrochemical catalyst can reduce the activation energy of the petrochemical reaction, so that the reaction can be carried out at a lower temperature and pressure, thus saving the petrochemical resources and energy. For example, the use of catalytic oxidation technology can oxidize ethylene to ethylene glycol under atmospheric pressure, while the traditional non-catalytic oxidation technology needs to be carried out under high pressure and consumes a lot of energy. Using catalytic synthesis technology, methanol can be synthesized to ether at low temperature, while traditional non-catalytic synthesis technology needs to be carried out at high temperature, which wastes a lot of resources.

 3. Expand new fields and products of petrochemical industry Petrochemical catalysts can create new reaction paths and new reaction mechanisms, and expand new fields and products of petrochemical industry. For example, the catalytic cracking technology can be used to produce basic petrochemical raw materials such as ethylene and propylene, which provide raw materials for polymer materials such as synthetic resin, synthetic fiber and synthetic rubber. Using catalytic polymerization technology, polyethylene, polypropylene and other plastics with excellent performance can be produced, which provide materials for packaging, construction, medicine and other industries. Organic intermediates such as styrene and benzyl alcohol can be produced using catalytic acid-base technology, which provides raw materials for pharmaceutical, pesticide, dyeing and other industries.
