In the field of petroleum processing, catalysts play a vital role. As a common catalyst, phosphoric acid composite catalyst is widely used in petroleum processing. In this paper, the application of phosphoric acid composite catalyst in petroleum processing is studied.

Phosphoric acid catalyst is widely used in catalytic cracking process. Catalytic cracking is an important petroleum processing technology used to break down heavier crude oil into lighter petroleum products such as gasoline, diesel, and lubricants. The phosphoric acid composite catalyst can be used as a catalyst for cracking reaction, which accelerates the reaction and improves the yield and quality of the product. By regulating the composition and structure of the phosphoric acid composite catalyst, the selectivity and yield of the cracking reaction can be further optimized, and the overall processing efficiency can be improved.

Phosphoric acid catalyst also has important application in lube oil processing. In the production process of lubricating oil, phosphoric acid laminated catalyst can be used to catalyze esterification reaction and desulfurization reaction. Esterification reaction can react organic acids and alcohols to produce esters, and desulfurization reaction can remove sulfides in lubricating oil and improve product quality. As an efficient catalyst, the phosphoric acid composite catalyst can promote these reactions at lower temperature and pressure, and improve the reaction rate and yield.

The phosphoric acid laminated catalyst can also be used in the process of petroleum hydrogenation and desulfurization. Petroleum hydrogenation is an important petroleum processing technology, which is used to remove sulfur, nitrogen and metal impurities in crude oil and improve fuel quality. The phosphoric acid superposition catalyst can be used as a catalyst for hydrogenation reaction. Through the action of catalyst and hydrogen, impurities in crude oil can be removed and the purity of the product can be improved. At the same time, the phosphoric acid composite catalyst can also be used in the desulfurization reaction to remove the sulfide in the fuel and reduce environmental pollution.

Phosphoric acid superposed catalysts have a wide range of applications in petroleum processing. Through the application of phosphoric acid composite catalyst, the efficiency and yield of cracking, lubricating oil processing, petroleum hydrogenation and desulfurization can be improved, and the quality of products can be improved. With the increasing demand for petroleum resources and the increasingly serious environmental pollution, the application of phosphoric acid composite catalyst in petroleum processing will continue to receive attention, and is expected to be further developed and innovated. The research and application of phosphoric acid catalyst will provide important support for the sustainable development of petroleum processing industry.
