Introduction of molecular sieve material
In the context of carbon neutrality, molecular sieves, a new material for adsorption and catalysis, have gradually attracted attention. A few days ago, at the 7th Molecular Sieve Technology and Application Summit Forum of Jianlong Micronano, more than 200 guests including China Gas Industry Association and heads of well-known domestic gas equipment companies gathered to discuss the application of molecular sieves in the energy, chemical industry and environmental fields.
Molecular sieve adsorbents screen the carbon dioxide, nitrogen and other components in the air through physical adsorption, so as to achieve the purpose of purifying the target gas. Because molecular sieve has the advantages of high adsorption capacity, strong selectivity, and high temperature resistance, it has been widely used in many fields such as petrochemical industry, coal chemical industry, air separation and purification, environmental management and so on.
At present, there are four major paths for feasible carbon neutral technologies, namely, energy transition, carbon capture and utilization, low-carbon life, and plant carbon sink. Liu Yingshu, director of the Institute of Gas Separation Engineering, University of Science and Technology Beijing and director of the Group Standards Committee of the China Gas Association, introduced at the forum that the above-mentioned technical paths can be found in the application of molecular sieves.
In terms of carbon capture and utilization, molecular sieve adsorbents and catalysts are used to collect and store carbon dioxide, so as to achieve industrial carbon emission reduction and utilization; in terms of plant transformation, zeolite water-retaining agents and repair agents are used to fix water for soil moisturizing and repair, so as to achieve deserts. Fixed water afforestation, saline-alkali land restoration, etc.
Data shows that steel plants across the country need a total of 130,000 tons of molecular sieve for oxygen production each year. In addition, in the field of hydrogen production, molecular sieves can not only be used for the recovery and purification of hydrogen in various industrial hydrogen-containing tail gas, but also help to reduce environmental pollution caused by tail gas emissions or direct combustion of tail gas.
In addition to the above fields, molecular sieves also play an important role in the utilization of nuclear energy. According to Liu Zhihui, director of the Nuclear and Radiation Safety Center of the Ministry of Ecology and Environment of China, as an inorganic ion exchanger, molecular sieves have the advantages of high radiation resistance, mechanical, thermal and ionization stability. Molecular sieves were used in the treatment of radioactive waste water in the nuclear accident at the Fukushima nuclear power plant in Japan, and good results have been achieved.
It is predicted that with the continuous growth of the oil and gas industry in emerging economies, the compound annual growth rate of the global molecular sieve market from 2020 to 2025 will be 5.65%, and it will reach 4.39 billion US dollars in 2025. On this subdivision track, there are already some listed companies with considerable strength.
