Résumé :

The effect of hydrogen partial pressure on the hydrogenation rate of lignite char has been studied at pressures between 0.3 and 1 atm and temperatures between 820 and 940°C by thermogravimetry. The apparent order as a function of hydrogen pressure and the activation energy of this reaction have been determined. Under the experimental conditions investigated in this work, after gasification of about 70% of the lignite char, the hydrogenation rate decreases rapidly. © 1979.
