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. |
