2-11　Mechanisms for the production of activated carbon from marine biomass resources

Abstract

When kelp, a marine biomass, was carbonized, it was found that numerous fine pores were formed, creating a porous carbon material similar to activated carbon. Analysis of the gas components generated during heating and the carbonized material after heating revealed that kelp and wakame have different carbide structures, which helped clarify the mechanism of activated carbon production. It was also suggested that the salts contained in seaweed may influence the changes in molecular structure during the carbonization process.
