Development of new macro-micro hybrid porous carbon materials with woodceramics

木材陶瓷（WCS）是一种新的多孔碳材料，它已被开发用于有效用途的废物木材。对启动木质材料的类型和形状的对应说明，如中等密度纤维板（MDF）和木质粉末，下面的两种方法通常用于准备WCS。在第一种方法中，WCS是由碳化的MDF浸渍准备的。在这种方法中，植入的phenolic resin改变了碳生成过程中的硬玻璃碳，并在MDF中重新发现了软木炭，该软木炭是由木纤维衍生而来的。在第二种方法中，WCS是由碳化的木材粉末和苯树脂粉末的紧凑混合物来准备的。因此， WCS是一种复合材料，其中含有大量的硬玻璃碳，来自木质纤维，其中含有苯树脂和软木炭的许多宏观纤维。在本研究中，订购使用这些MDF-和粉末方法WCS作为广告商。 ...

Woodceramics (WCS) are new porous carbon materials which were developed for the purpose of the effective use of waste wood. Corresponding to the kind and shape of starting wood materials such as medium density fiber board (MDF) and wood powder, the following two methods are usually used for preparing the WCS. In the first method, the WCS are prepared by carbonizing the MDF impregnated with liquid phenolic resin. In this method, the impregnated phenolic resin changes into hard glassy carbon during carbonizing process and reinforces the soft charcoal which originated from wood fibers in the MDF. In the second method, the WCS are prepared by carbonizing the compacted mixtures of wood powder and phenolic resin powder. Therefore, WCS are composite materials with hard glassy carbon containing a lot of micro pores originated from phenolic resin and soft charcoal containing many macro pores originated from wood fibers.In this study, in order to use these MDF- and powder-method WCS as the adsor … More bents for harmful gasses and humid (vapors), the effects of carbonization temperature, phenolic resin content and the kind of original wood on the specific surface area were examined by BET method. The results obtained are as follows :(1)The specimens prepared by the powder-method showed larger specific surface area than the specimen prepared by MDF-method, namely 380m^2・g^<-1> in the powder-method specimen containing 30% phenolic resin carbonized at 700℃ and 280m^2・g^<-1> in the MDF-specimen containing 30% phenolic resin, respectively.(2)The power-method specimen containing larger amount of phenolic resin showed larger specific surface area, namely 450m^2・g^<-1> in the specimen containing 70% phenolic resin carbonized at 700℃, 380m^2・g^<-1> in the specimen containing 30% phenolic resin and 230m^2・g^<-1> in the specimen containing 10% phenolic resin, respectively.(3)The softwoods with low bulk density showed larger specific surface area than the hardwood with high bulk density, namely the specific surface areas of softwood (Matsu and Sugi in Japanese) were 450-400m^2・g^<-1> carbonized at 800℃ and that of the hardwood (Ubame-Gashi in Japanese) was 330m^2・g^<-1>, respectively.(4)Therefore, the combination of softwood powder and phenolic resin powder in the powder-method will give the largest specific surface area on carbonization at 800℃.
