植物種子有用成分抽出残渣を原料とする活性炭の製造

Abstract

The purpose of the present work is to study the feasibility of production of active carbon from extraction residues of a seed plant such as jatropha curcas， coffee， etc. The extraction residues were at frrst carbonized and then activated by steam. The effects of activation conditions on the characteristics of the active carbons obtained were experirnentally investigated. From all the raw material employed， active carbons having a relatively high specific area could be produced， and these are rich in micro-pores to diameter 0.5～0.8nm. From these results， it seems that the waste of solid state medium like the extraction residue of seed plant can be reutilized as the raw material of active carbon.
