Introduction to Carbon Molecular Sieve for PSA Nitrogen Generation With the wave of industrial revolution in the 1950s, the application of carbon materials became increasingly widespread, with the fastest expanding field being activated carbon, which gradually developed from filtering impurities to separating different components. At the same time, with advances in technology, human processing capabilities of matter became stronger, under which carbon molecular sieve was born. In the 1960s, carbon molecular sieves was successfully manufactured and quickly promoted in the United States. Initially, it was used as adsorbents to separate oxygen from air and gradually applied to devices for producing nitrogen.…
