Heteroatom removal of dibenzofuran, dibenzothiophene, and carbazole and hydrogenation of anthrathene and pyrene were investigated in the presence of FeS_2, NiMo/Al_2O_3 and Ru/SiO_2・Al_2O_3 as catalysts by a high pressure DTA technique and autoclave test. In the case of dibenzothiophene, nuclear hydrogenation and HDS proceeded at the temperature below 300℃ and the hydrocracking proceeded over 300℃. Dibenzofurane was hydrocracked and hydrodeoxygenated over 300℃ in the presence of FeS_2 and NiMo catalysts, but Ru/SiO_2-Al_2O_3 catalyst was activeat about 200℃ for it. Carbazole was stable until 350℃ for HDN, but Ru/SiO_2・Al_2O_3 catalyst was very active for nuclear hydrogenation belowm. p.. Finally, anthracene and pyrene were stable for hydrocracking until 450℃, but easily hydrogenated.
