| Abstract: | The chemisorption of oxygen (P = 1 atm, flow rate, 200 ml min?1) by an anthracite from Peñarroya and on other adsorbents prepared from the starting sample has been studied in isothermal and dynamic conditions using gravimetric methods.Hypotheses to justify the thermograms have been established and comparative information on the energetic aspects determining both gasification stages has been obtained.Some kinetic and thermodynamic aspects are studied from oxygen chemisorption isotherms. |
