| Abstract: | To determine effective surface self-diffusion coefficients of CO2 within type 13X zeolite particles, at various temperatures (25–70 °C), inverse analyses of observed CO2-uptake curves were successfully performed. The obtained effective surface self-diffusion coefficients increase with both the amount adsorbed and the temperature and ranged from 7.8 × 10?10 to 1.95 × 10?9 m2/s under the present experimental conditions. |
