Production of activated carbon via oxidation with K2Cr2O7 and chemical treatment

Abstract EN

In this work activated carbon of good quality prepared using oxidation condensation process.

The oxidation of the asphlatic materials was conducted using several percentage of K2Cr2O7 and in the presence of a stream of air or oxygen.

The reaction mixture was heated at 350°C for 3hrs.

This followed by removal of uncarbonized materials under reduced pressure.

The condensation of the fraction obtained is expected to recombine or rereact to give a high carbon content.

The carbonization and activation was conducted at 550±25°C for 3hrs.

and the ratio of the feedstock to NaOH was (1:2).

After the carbonization was completed, the reaction mixture was subjected to purification by treatment with 10% HCl and distiller water till it gives neutral test to the litmus paper.

The samples were dried at 120°C for 24hrs.

and its physical properties were determined.

The research work indicated that a good quality activated carbon can be obtained when the oxidation of sample was conducted using 3% K2Cr2O7.
