Abstract: | Co-pyrolysis at relatively low temperature (673 K) and high pressure (10 MPa), using three organic compounds, was used to
modify the porosity of the two ACs. The co-pyrolysis is effective for the modification of the porosity of an AC, and the efficiency
depends on the organic compound used. The differences found are consequence of the chemical composition of the organic precursor.
High pressure pyrolysis produces beneficial results when an organic compound that volatilizes during the preparation is used.
Conducting pyrolysis at low temperature permits improved control of the porosity because the rate of gasification can be more
tightly controlled. |
