High Purity Synthetic Carbon Adsorbents for Challenging Separations

3. February 2021 | 14:00-15:00 (CET)

Novel nanoporous materials for purifications and separations of gas and liquid streams.

Novel spherical polymer-based carbon particles can be used in coatings or in packed bed systems. These adsorbents can be used for separation of volatile compounds in gas streams, for purification of air and permanent gases, and separation of dissolved molecules in liquid streams.

Carboxen carbons are part of the Supelco line of commercially-available carbons. Carboxen particles are synthetic carbons that are spherical, have a narrow particle size distribution, and pre-defined pore structure and surface chemistry. Carboxen 569 possesses a hydrophobic surface and has an increased kinetic saturation capacity for volatile organic compounds such as dichloromethane, butane, pentane and vinyl-chloride.

Breakthrough analysis of dissolved organic molecules demonstrates significantly increased retention volume with Carboxen particles as compared to granular activated carbon (GAC). Carboxen 1032 having 16% of oxygen functionalities and an acidic surface increased the retention volume of organic amines while Carboxen 1034 having basic surface chemistry retained organic acids such as benzoic acid. Due to their limited surface chemistries, as well as the inability to control particle size and tailor pore size distribution, GACs were outperformed by specialty polymer-based carbons.

Target audience

Managers of Process Development, Scale-up, Pilot Plants and Production in Chemical and Industrial Gas Manufacturing, also Medical Device.
