Carbon fiber composite molecular

A recently developed adsorbent version of ORNL s porous carbon fiber-carbon binder eomposite is named carbon fiber composite molecular sieve (CFCMS). The CFCMS monoliths were the product of a collaborative researeh program between ORNL and the University of Kentueky, Center for Applied Energy Researeh (UKCAER) [19-21]. The m.onoliths are manufactured in the manner deseribed in Section 2 from P200 isotropic pitch derived fibers. While development of these materials is in its early stages, a number of potential applieations can be identified.

Oak Ridge National Laboratory (ORNL) has developed a carbon fiber composite molecular sieve designed specifically to absorb CO2 emitted from coal fired power plants and gas turbines. Petroleum pitch based chopped fiber is bonded with a phenolic resin and activated in steam, O2, or CO2 at 850°C, to form a product with a large surface area and pore volume with mesopores of 2 50 nm, capable of absorbing CO2. There are also macropores (50 100 pm) which allow sufficient fluid flow with low pressure drop. It also has potential to be used for removal of CO2 from natural gas for fuel cells. [25].
