Preparation and modification of activated carbon from oil-palm shell and its adsorption capacity through speciation of chromium

A preparation and modification of activated carbon from oil-palm shell has been investigated in this paper. A pretreatment method has been established to avoid partial fusion and swelling in the carbonization stage. Carbonization has been studied at different temperatures and the structure of the mi...

description A preparation and modification of activated carbon from oil-palm shell has been investigated in this paper. A pretreatment method has been established to avoid partial fusion and swelling in the carbonization stage.

Activated carbon has been prepared from steam gasification of chars obtained at 800 OC. This activation increases both total and narrow microporosity and develops a substantial mesoporosity. Activated carbon with different pore size distribution is impregnated with zirconium chloride and iron chloride salts to give impregnated carbon with different metals loading.
