Titanium-silicon molecular sieve can be used in HPPO process, and titanium-silicon molecular sieve TS-1 is its representative product.

​​​​Titanium-silicon molecular sieves are zeolite molecular sieves, which refer to a type of heteroatom molecular sieve that introduces titanium atoms into the skeleton. Titanium silicon molecular sieve has the advantages of good chemical stability, strong hygroscopicity, long service life, and green environmental protection. As a catalytic oxidation catalyst, it has broad application prospects in chemical industry, wastewater treatment and other fields.

There are many types of titanium-silicon molecular sieves. Titanium-silicon molecular sieve TS-1 and titanium-silicon molecular sieve TS-2 are their representative products. Among them, titanium-silicon molecular sieve TS-1 occupies a large share of the market. Titanium silicon molecular sieve TS-1 has a special topological structure, has both shape-selective catalysis and catalytic oxidation activity, and is widely used in green catalytic oxidation systems. my country’s titanium silicon molecular sieve TS-1 was domestically produced in 2012. After years of development, the technological maturity of local companies has continued to improve, and product performance and quality have been further improved.

According to the “2023-2028 China Titanium Silicon Molecular Sieve Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, Titanium silicon molecular sieves are widely used in chemical industry and wastewater treatment and other fields. In the field of chemical industry, titanium silicon molecular sieve can be used to prepare chemical products such as butanone oxime and propylene oxide. In recent years, benefiting from the deepening of the concept of green environmental protection, the HPPO process, as a green propylene oxide preparation process, has gradually become one of the global research hotspots. As the main catalyst used in the HPPO process, titanium-silicon molecular sieve has the characteristics of no pollution and mild reaction conditions. Advantage. Driven by downstream demand, the development speed of the titanium silicon molecular sieve industry has further accelerated.

​​ ​​The major global manufacturers of titanium-silicon molecular sieves include Italian EniChem Company, American Engelhard Company, etc. In terms of the local market, the main manufacturers of titanium silicon molecular sieves in my country include China Catalyst, Yida Co., Ltd., etc. China Catalyst is my country’s leading titanium-silicon molecular sieve company. It focuses on the R&D, production and sales of molecular sieves and non-molecular sieve catalytic materials, mobile source denitrification, titanium-silicon molecular sieves and other products. Its independently developed titanium-silicon molecular sieve TS-1 has been widely used in HPPO method to produce propylene oxide and HAO method to produce caprolactam and other processes.

Titanium silicon molecular sieve is a commonly used catalyst. Attracted by the market prospects, my country’s research enthusiasm for titanium silicon molecular sieve continues to rise. In September 2022, Professor Guo Xingxin’s team from the School of Chemical Engineering of Dalian University of Technology successfully prepared a monolithic titanium-silicon molecular sieve catalyst based on the chemical engineering principle relationship between catalyst thermal conductivity and stability. Compared with conventional extruded catalysts, this product has bed laminated pressure It has the advantages of small drop rate, good thermal stability, and simple loading. It will be used in the epoxidation reaction of 1-butene in the future.

Industry analysts said that titanium silicon molecular sieve has the advantages of good chemical stability, green and environmental protection, and is widely used in fine chemicals, petrochemicals and water. The processing field has broad application prospects. In recent years, driven by the national “double carbon” goal, my country’s HPPO legal propylene oxide technology has continued to make breakthroughs, providing favorable conditions for the development of the titanium silicon molecular sieve industry.
