    • The invention relates to a method for producing shaped, activated charcoal. According to the method, after being ground, carbon-bearing material, or a mixture of several carbon-bearing materials are rendered homogenous with a binding agent which contains water, or a mixture of several binding agents, at least one of which contains water. The mixture of carbon-bearing material and binding agent is then formed into shaped bodies. According to the invention, in order to consolidate the grain formation, these are dried until they exhibit a maximum total water content of 3 % by wt. in relation to the shaped body. The shaped bodies which have been formed and dried in this manner are then subjected to a carbonization and subsequently a gas activation process.
    • 本发明涉及一种用于生产成型,活性炭的方法。 为了这个目的,碳质材料或几种碳质材料与含水结合剂或几种的结合剂,其中至少一种是水合的,均匀混合的混合物研磨后的混合物中。 然后,碳质材料和粘合剂的混合物成形,得到的模制品。 这些都是用于根据本发明的至多3重量的.-%的总水含量的基础上,干燥片剂重量强化晶关联。 将如此成形和干燥的成型体随后进行碳化,最后进行气体活化。

    • A method of forming activated carbon from microcrystalline cellulose comprises converting the microcrystalline cellulose powder into microcrystalline cellulose beads using extrusion and spheronization, carbonizing microcrystalline cellulose to form carbonized microcrystalline cellulose and activating the carbonized microcrystalline cellulose to form activated carbon. The final size of the activated carbon beads, which preferably are of practically spherical shape, can be controlled through the process of making microcrystalline cellulose beads. The invention also encompasses carbon beads having pores therein comprising a majority of the pores less than about 30A and a micropore volume calculated using Density Functional Theory (DFT) in the range of about 0.2cm3/g to 1.0cm3/g for pores in the range of about 5A to 10A. The invention also encompasses a smoking article filter comprising such activated carbon beads, a method for making such a filter and a method for making a smoking article including such a filter.
    • 由微晶纤维素形成活性炭的方法包括使用挤出和滚圆将微晶纤维素粉末转化为微晶纤维素珠粒,将微晶纤维素碳化以形成碳化微晶纤维素并活化碳化微晶纤维素以形成活性炭。 可以通过制造微晶纤维素珠的过程来控制优选实际上球形的活性炭珠的最终尺寸。 本发明还包括其中具有孔的碳珠,其中大部分孔小于约30A,并且使用密度泛函理论(DFT)计算的微孔体积在约0.2cm 3 / g至1.0cm 3 / g的范围内, 约为5A至10A。 本发明还包括包含这种活性炭珠的发烟制品过滤嘴,制造这种过滤嘴的方法和制造包括这种过滤嘴的发烟制品的方法。
