Applications of Pressure Swing Adsorption Technology in Chemical Industry

The pressure swing adsorption technology is mainly applied in C1 chemistry in the chemical industry. Does anyone know where objects like daily beverage bottles, sofas, quick-drying T-shirts come from? They were all produced by petroleum cracking and then through other synthesis procedures step by step. As we know China is rich in coal and poor in oil. In resent 20 years, the “coal chemical industry” that has been developing is to use coal instead of oil to produce our daily necessities.

So how does the coal chemical industry turn coal into the clothes we wear, the seats we sit on and the water cups we use? The principle is: the coal is gasified through a gas making furnace where the most useful gases such as CO and H2 are separated by pressure swing adsorption technology and then put into use in chemical synthesis, which will eventually produce those daily necessities. In this process, pressure swing adsorption technology must be adopted to solve some technical difficulties. For instance, to achieve efficient separation of CO from N2 or CH4, the pressure swing adsorption technology using copper-based adsorbent is on the must list. China has independent property rights for the technology and has stayed ahead of the international level.
