PROCESS FOR PRODUCTION OF AROMATIC HYDROCARBONS

摘要

The invention aims at providing a process for the production of aromatic hydrocarbons with a molybdenum-containing solid catalyst in which the molybdenum-containing solid catalyst is activated and thereby attains high yield for a long time to enable efficient production of aromatic hydrocarbons from a lower hydrocarbon gas containing methane as the main component. A process for the production of aromatic hydrocarbons which comprises both the preliminary contact step of preliminarily bringing a molybdenum-containing solid catalyst into contact with one or more preliminary contact gases selected from among lower hydrocarbons and hydrogen gas and the reaction step of bringing the resulting catalyst into contact with a raw material gas containing methane as the main component to conduct reaction and thus produce aromatic hydrocarbons, characterized in that the initiation temperature of the preliminary contact is lower than the reaction temperature and the preliminary contact temperature over the period from the initiation to the end does not exceed the reaction temperature.
