Textural Development of Activated Carbon Prepared from Recycled PET with Different Chemical Activation Agents
Activated carbons (AC) were prepared from waste granulated Polyethyleneterephthalate (PET) by chemical activation with phosphoric acid, sodium hydroxide and potassium hydroxide. All AC were characterised by N2 adsorption at 77 K, and those prepared with H3PO4 had a narrow pore size around 0.8 nm, th...

| description | Activated carbons (AC) were prepared from waste granulated Polyethyleneterephthalate
(PET) by chemical activation with phosphoric acid, sodium hydroxide and potassium hydroxide.
All AC were characterised by N2 adsorption at 77 K, and those prepared with H3PO4 had a narrow
pore size around 0.8 nm, those prepared with NaOH had a larger pore size higher than 1.52 nm and
those prepared with KOH presented a pore size varying between 0.66 and 1.58 nm. The results
suggest that H3PO4 and NaOH are not the most suitable activating agents for preparing AC with a
high pore volume from waste PET. The AC produced with KOH presented a very high porosity,
which passed through a maximum of 0.75 cm3g-1, due to an enlargement of the small micropores
with an increase of the carbonisation temperature. |
