Coconut Shell Activated Carbon

The production of Coconut Shell Activated Carbon treated with

phosphoric acid was optimized using the response surface

methodology.Individual second-order response surface models were

developed and contour plots were generated for the optimization

analysis.

A series of activated carbons was prepared from coconut shell

impregnated with phosphoric acid using a one-step carbonization

procedure and varying conditions in order to optimize preparation

parameters. The mode and nature of gaseous flow during

carbonization were found to affect the surface area and yield,

suggesting that oxygen derived from the gas phase may play an

important role in activation, and that coking of volatiles could

be contributing to the building of the porous structure.

These were all significantly more intense in the carbons prepared

with phosphoric acid as compared with a standard prepared using

high-temperature activation.
