説明

The combination process comprising successively of catalytic aromatization and thermal hydrogenolysis for naphtha, kerosene and gas oil was studied using a flow system in the presence of hydrogen. Aromatization was carried out over a commercial chromia-alumina catalyst at temperatures ranging from 520 to 560°C under an atmospheric pressure, while hydrogenolysis ranging from 735 to 752°C.<br>Main liquid products at operating conditions specified above were mostly composed of aromatic hydrocarbons and neither paraffins nor olefins higher than benzene. Productions of aromatics and gaseous olefins were 60∼74% in weight for naphtha, kerosene and gas oil, respectively. It was found that a considerable amount of naphthalene and its derivatives was formed in the combination processing of both kerosene and gas oil.
