    • To improve stability of catalytic performance, an aromatizing catalyst for converting lower hydrocarbons into aromatic compounds is regenerated. A regeneration process of the aromatizing catalyst according to the present invention includes the steps of: (a) reacting the aromatizing catalyst with a hydrogen gas in an atmosphere containing the hydrogen gas after using the aromatizing catalyst in an aromatizing reaction for converting lower hydrocarbons into aromatic compounds; (b) decreasing a temperature of the atmosphere containing the hydrogen gas reacted with the aromatizing catalyst, by supplying one of an inert gas and a reducing gas to the atmosphere; (c) reacting the aromatizing catalyst reacted with this inert gas, with an oxidizing gas; and (d) reacting the aromatizing catalyst reacted with the oxidizing gas, with a reducing gas.
