As the first adsorbent for nitrogen making, carbon molecular sieve has been widely used in air separation to produce nitrogen rich gas. In China, gradually occupy the market share of domestic adsorbent carbon molecular sieve. In the next few years, the adsorbent carbon molecular sieve products will be developed to high index, high strength, high bulk density direction, some low-grade products will be eliminated. And nitrogen making machines tend to be miniaturized.
With the constant development of PSA technology, the application field of nitrogen making machine has become more and more broad. The demand for nitrogen making machines in Europe and the United States is increasing every year. In recent years, the demand in some developing countries is also advancing by leaps and bounds, and the annual growth rate is also very fast. The increase of the demand of nitrogen making machine has promoted the rapid development of carbon molecular sieve for the adsorbent of nitrogen making machine.
According to the analysis of international and domestic experts, carbon molecular sieve industry has the following trends: first, with the use of PSA nitrogen machine continues to expand, increasing the demand for carbon molecular sieve, which will further promote the development of the industry, the next few years, the industry will be a rare industry becomes as everyone knows. Secondly, with the increase of the depth of application, carbon molecular sieve nitrogen yield and nitrogen recovery rate, bulk density, compressive strength and other indicators of the increasingly high demand, further improve product performance index will be the trend in the future development of the industry. Third, because the carbon molecular sieve is the main component of the pressure swing adsorption nitrogen making machine, the cost is more than 70% of the whole equipment. Therefore, the cost of reducing the adsorbent cost of nitrogen making machine will be an important condition to promote the development of the industry. In recent years, the state attaches great importance to coal mine safety, mandatory coal mine industry equipped with nitrogen making machine, expanded the demand for domestic carbon molecular sieve, so the market demand for nitrogen sorbent in the future is very large.
