Carbonization of bamboo by dry steam and the adsorption characteristic of the product

摘要

Since bamboo is inclination material with pores of various sizes, there is possibility of the alternative adsorbents of substances. So, absorbents from bamboo are also expected as a material for cleaning water. However, activated carbon is expensive. Then, in order to reduce cost, it is necessary to develop a new carbonization process.Here, we proposed the original process of carbonization by dry steam which set two generation processes to one. Its stage is simple and it is a reaction at low temperature (300 °C) compared with the generation method.In this experiment, we developed non-equilibrium reaction equipment and conducted by changing reaction conditions. Products were analyzed by the observation of their surface and weight change, and investigated the relation characteristic between reaction and water. Then, adsorption of chloroform onto the products was investigated.As temperature became high, the weight loss became more remarkable with the dry steam. Therefore, it is supposed that dry steam is promoting the carbonization reaction. And the adsorption onto the product (at 300 °C) is higher than the activated carbon. It can be very significant, since it is a reaction in low temperature compared with the generation method.
