What are the uses of catalysts in petrochemical products
For example, the production cost of ethylene glycol, the cost per unit of oxygen and ethylene accounts for 85-90% of the cost, while the consumption of the two mainly depends on the selectivity of the catalyst. Therefore, the core competition of ethylene glycol unit is the competition of catalyst. The high selectivity catalyst not only directly determines the unit cost of raw materials such as ethylene and oxygen, but also produces less by-products and impurities.
The selective oxidation products occupy 80% of the total amount of chemical products, and the catalyst is required to have high catalytic selectivity. The selective oxidation catalyst can be divided into gas solid phase oxidation catalyst and liquid phase oxidation catalyst.
Most of the processes for the production of oxygenated products in petrochemical industry are selective oxidation processes
