For a long time, carbon molecular sieves have been monopolized by Japan and Germany. Before 2000, they occupied 80% of the domestic market, especially in the international market. With the growth of domestic carbon molecular sieve manufacturers, domestic molecular sieves gradually seize most of the market share. However, in order to become bigger and stronger in this industry, we must innovate independently, improve product performance indicators and break technical barriers.
In the next few years, carbon molecular sieve products will develop towards high index, high strength and high bulk density, low index and low-grade products will be eliminated, and the air separation equipment will tend to be miniaturized, which puts forward higher requirements for the molecular sieve industry. Therefore, if we seize the current good opportunity, improve quality and expand production, It will be the goal of every domestic carbon molecular sieve manufacturer to gradually change the international and domestic cognition of low price and low quality of domestic carbon molecular sieve and quickly seize the domestic and international market.
In 2012, medium and low-grade carbon molecular sieves were mainly used in the domestic market, with a total annual demand of more than 6000 tons. With the continuous development of China's economy, the scale of industry, especially chemical industry, continues to expand, and the demand for carbon molecular sieves will increase year by year. Especially in recent years, the state has attached great importance to the safety of coal mines, oil fields and oil tankers, and forced oil fields and oil tankers to be equipped with nitrogen generators, The demand of electronic industry and material industry has further expanded the demand of domestic carbon molecular sieve. According to the survey, since 2000, the average annual growth rate has been more than 80%, and the market prospect is very broad.
In the international market, with the continuous maturity of pressure swing adsorption technology, the application field of nitrogen generator is wider and wider, and the demand for carbon molecular sieve is also greater and greater. The demand of developed countries such as Europe and the United States is growing steadily every year. In recent years, the demand of developing countries is advancing by leaps and bounds, increasing at a double rate every year. It is conservatively estimated, In 2013, the total international demand for carbon molecular sieve was more than hundreds of thousands of tons.
According to the analysis of international and domestic experts, the carbon molecular sieve industry shows the following development trends: first, with the continuous expansion of the application scope of pressure swing adsorption nitrogen generator and the increasing demand for carbon molecular sieve, this will further promote the development of the industry. In the next few years, this industry will become well-known from a remote industry. Secondly, with the improvement of application depth, the requirements for nitrogen production, air nitrogen ratio, bulk density, compressive strength and other indicators of carbon molecular sieve are higher and higher. Further improving product performance indicators will be the general trend of the development of this industry in the future. Third, carbon molecular sieve is the main component of PSA nitrogen generator, and the cost accounts for more than 70% of the whole equipment. Therefore, reducing the cost will be an important condition to promote the development of this industry. In the coming period, enterprises will continue to explore the use of new materials and new processes, and strive to reach the highest level with the lowest cost.
After more than 20 years of development, domestic carbon molecular sieves have made breakthrough progress, with nitrogen production reaching 220 to 260nm3 / H.T. Through the comparison between the carbon molecular sieve produced by our company and the carbon molecular sieve of foreign brands on the same model for many times by domestic and foreign nitrogen generator manufacturers, it is proved that the technical quality of the carbon molecular sieve produced in China has ranked among the world's advanced ranks, in which the gas production performance and time response have exceeded the international level, and has been highly praised by the PSA nitrogen production industry at home and abroad. Carbon molecular sieve products have been widely used in coal field, petroleum, chemical industry, metal heat treatment, electronic manufacturing, food preservation and other industries in China, and exported to the United States, Europe and Asia. Its export volume has already exceeded the import volume of that year, rewriting the history of no export of carbon molecular sieve in China, and realizing the second leap from import to export!
While domestic carbon molecular sieves sell well all over the world with high quality and low price, there is still a lot of work to be done for carbon molecular sieves and nitrogen production units. First, actively develop environment-friendly carbon molecular sieve production process to create a foundation for the development of carbon molecular sieve enterprises to large and medium-sized enterprises; Second, the carbon molecular sieve brand can be subdivided into energy-saving type, common nitrogen type and long-term type according to the process requirements of different nitrogen use places; Moreover, in the industry, actively explore the development mode of friendly competition among peers, such as strong alliance and capital alliance, so as to create international brand enterprises.
