                         in the direct liquefaction process of high volatile bituminous 
                         coal from the south of Brazil. The process consisted of mixing 
                         pulverized coal with tetralin in the presence of catalyst. It was 
                         possible to obtain fractions of preasphaltenes, asphaltenes, and 
                         oils. Pressure had little influence on the direct coal 
                         liquefaction process, while temperature had a strong effect on 
                         liquefaction yields. The results of total conversions obtained 
                         were nearly 16 % at 300 °C, 26.5 % at 350 °C and 38.5 % at 380 °C, 
                         in spite of high inertinite-group maceral content (34 vol.%). The 
                         pyrite ore catalyst had a fundamental role in this reaction, 
                         leading to thermal cracking of the coal structure and 
                         hydrogenation of the fragments. However, the most significant 
                         result related to catalyst presence was the increase in 
                         selectivity of the oil fraction.",
