The coal partial hydro-pyrolysis process (ECOPRO) is under development to produce synthesis gas and light oil such as naphthalene. It is thought that naphthalene is formed by hydrogenation of the heavy tar which is produced by primary pyrolysis of coal. At the same time, naphthalene is partly disintegrated to benzene and methane. Therefore, it is supposed that both reaction of forming and pyrolysis participate in naphthalene yield. In this study, the partial hydro-pyrolysis of naphthalene was carried out. Stability of naphthalene was investigated with a unique batch reactor by changing the hydrogen partial pressure. As a result, the degradation of naphthalene was not promoted at the condition of partial hydro-pyrolysis in 0.9MPa hydrogen partial pressure compared to pyrolysis within no hydrogen. On the other hand, the degradation of naphthalene was promoted by hydro-pyrolysis in 3.0MPa hydrogen pressure. It was recognized that the partial hydrogenation atmosphere is available for the acquisition of naphthalene from coal.
