POROUS CARBON MATERIALS AND SMOKING ARTICLES AND SMOKE FILTERS THEREFOR INCORPORATING SUCH MATERIALS |
摘要 |
A porous carbon material suitable for incorporation in smoke filters for cigarettes has a BET surface area of at least 800 m<2>/g and a pore structure that includes mesopores and micropores. The pore volume (as measured by nitrogen adsorption) is at least 0.9 cm<3>/g and from 15 to 65% of the pore volume is in mesopores. The pore structure of the material provides a bulk density generally less than 0.5 g/cc. The material may be produced by carbonising and activating organic resins and may be in the form of beads for ease of handling. |
