| Résumé : | This study investigates the catalytic coal hydrogenation reaction in the presence of various alkaline salts. The influence of several parameters (temperature, hydrogen pressure, salt content) was investigated. The experiments were carried out in a thermobalance under pressure. The exhaust gases were analysed by gas chromatography, and the coke residues examined by scanning electron microscopy. The main conclusion that can be drawn from these investigations is that the presence of alkaline salts considerably increases the hydrogenation rate and yield of the analysed coals, in the efficiency order K 2CO 3 ≫ Na 2CO 3 ≫ K 2SO 4 ≫ KCl. © 1984. |
