Resumen:
In this work, the influence of the activation time on the development of the porosity is studied for carbons activated by means of a mixture of water vapor and nitrogen. The study is based on the application of three different methods of analysis: the well known DFT method, an analytical method base don a combination of the BET and Kelvin equations, and a Monte Carlo simulation method. These methods are applied to experimental data of nitrogen adsorption isotherms at 77K for a series of activated carbons obtained under carefully controlled conditions. Results turn out to be consistent among the three methods, leading to reliable conclusions about the influence of the activation time on the characteristics of the obtained carbons.
