Study on pore structure of woodceramics

WCS is a new porous carbon material of low cost and excellent properties, which is obtained by carbonization of middle density fiberboard impregnated with 40% PF resin. Pore structure was measured by low temperature N2 absorption method. WCS which is obtained by carbonization of middle density fiberboard impregnated with fireretardant and 20% PF resin is called P-WCS. Results showed that adsorption properties of traditional charcoal were very poor because of not being activated. Micropore area of WCS was 314.16 m2/g, and micropore volume was 0.1262 mL/g, which are much more than those of charcoal. Average diameter of WCS was 1.598 nm, which is much less than that of charcoal. PF resin brought lots of micropores into The WCS to have adsorption properties much better than those of charcoal.
