In order to investigate the behaviour of n-paraffins in secondary hydrogenation of coal liquid, hydrocracking of eicosane (C<SUB>20</SUB> n-paraffin) was carried at 375-475 °C under the hydrogen initial pressure of 80 kg/cm<SUP>2</SUP> . The conversion of eicosane and the product distribution were determined by a gas-chromatography to study the additional effects of various organic compounds and catalysts on the reaction of eicosane.<BR>The thermal hydrocracking of eicosane at 450°C for 1 hr was notably depressed by the addition of tetralin, quinoline or a poly-condensed aromatic compound, but slightly by the addition of trans-decalin or octylbenzene.(Table 1)<BR>The conversion of eicosane and the product distribution were little effected by the presence of Ni-Mo/Al<SUB>2</SUB>O<SUB>3</SUB>, but Ni-W/SiO<SUB>2</SUB>-Al<SUB>2</SUB>O<SUB>3</SUB> (calcined) promoted the hydrocracking of eicosane, which increased the iso-paraffins in the products remarkably.(Fig.2)
