CARBON FIBER CARBON MOLECULAR SIEVE
 
Gas separation, waste treatment, and catalyst supports are common industrial uses for active carbons. Settling, channeling, and pressure loss during operation are major problems associated with typical granular activated carbons. A novel process has been developed to produce a porous carbon fiber carbon composite with a density less than 0.2 g/cc. This composite can be activated to produce a significant volume of mesopores (2 to 50 nm). Furthermore, the rigid structure has macropores in the range of 50-100 microns which allow for excellent fluid flow through the sample, resulting in a low pressure drop. The rigid nature of the composite also eliminates channeling and settling, therefore making it a possible candidate for a catalyst support.
