We are the founding and board member of the Consortium of Pressure Swing Adsorption Technology for Gas Separation that is attached to the Society of the Machinery Industry Gas Separation Device and Equipment of China. Changxing Zhongtai is one of the leading players/companies in the field of carbonaceous porous materials especially in the field of carbon molecular sieves. We have expertise and well-established track record in the production of carbon molecular sieves for air separation for nearly twenty years, and have developed long-term cooperation relationship with outstanding talents and experts in research institutes and universities in China that will supply timely technical support.

The quality and separation performance of our products, i.e. carbon molecular sieves for air separation, are first-rate. The carbon molecular sieves have been widely applied as the indispensable adsorbent in PSA Nitrogen Production Units made in China and abroad to a number of countries in Asia, Europe and America.

Since 2004, the production of carbon molecular sieves in our company has been certified by the ISO9001:2000 standard. In 2006, a branch company, the Guangde Zhongtai New Carbon Materials Co.,Ltd was established, and started to operation in the same year. This further strengthens our company’s leadership in the quality and production capability of carbon molecular sieves for air separation in China.
