| Popis: | The hydrogenation of the coal model compound phenanthrene was investigated using a molten hydroxide-carbonate catalyst. The rate of catalysed hydrogenation was found to be approximately an order of magnitude greater than the uncatalysed reaction. Batch experiments were conducted at 20.7 MPa hydrogen pressure in a 1-l top-stirred autoclave at 480 °C for reaction times up to 1 h. Spinning-band distillation and gas-liquid chromatography coupled with mass spectrometry were used to separate and identify reaction products. Principal hydrogenation products were 9,10 dihydrophenanthrene and 1,2,3,4-tetrahydrophenanthrene. In addition, substituted naphthalenes and biphenyls were formed by hydrocracking of these two compounds. A similar product distribution was reported by others for an investigation of the thermal high-pressure hydrogenolysis of phenanthrene. The rate of the thermal reaction, however, was considerably lower. |
