Abstract
The hydrogenolysis of Solvent-Refined Lignite (SRL) obtained from Morwell coal was conducted in the presence of four kinds of catalysts with tetra-lin or creosote oil as solvent at 693 K. The products were separated into five compo-nents and each of them was analyzed by 1H-NMR. With Adkins' catalyst, hydrogena-tion of aromatic nuclei predominates over cleaving linkages between the structural units. The catalysis of Fe2O3+ S is similar to that of Adkins' catalyst but the former is less active. MoO3-TiO2 is the most powerful catalyst for the hydrogenolysis of SRL among the catalysts employed here and it seems to contribute to cleaving linkages be-tween the structural units. The catalysis of MoS3-Al2O3 is similar to that of MoO3-TiO2 in the presence of solvent. Asphaltenes and Insolubles decrease with reaction time. However, after a certain composition of the products reaches, decom-position of naphthenic structures seems to occur accompanied by its dehydrogenation. It was concluded that the specific behavior of each catalyst for the hydrogenolysis of the SRL agrees with that for the reactions of the model compounds.
