Abstract

This paper deals with a method to produce carbonaceous adsorbents from biomass using a technique of aqueous phase carbonization (hydrothermal carbonization). A series of laboratory-scale tests to produce carbonaceous materials from existing biomass such as Japanese cedar, which is a typical construction material in Japan, were conducted. The biomass feedstock was subjected to (1) hydrothermal carbonization at 350C, followed by (2) hydrothermal oxidation at 350C with the existence of hydrogen peroxide and (3) short-tome heat treatment at 950C in a closed crucible with no water. Thus-obtained carbonaceous materials were found to have mesoporous structures with ca. 350 m2/g of specific surface area and the adsorption capacity for phenol could reach to around three-quarters of that of a commercial activated carbon.
