Abstract: By combining results of transient response tests with forced concentration oscillation experi-ments,behaviors of benzene oxidation over V_2O_5 catalysts has been determined.Product increse canbe observed during periodic operation.The mechanism of catalytic reaction can be elucidated andthe behavior of concentration oscillation during the reaction is determined.The relation betweencycling frequency and response characteristics has also been studied with two different types of peri-odic operation,i.e.,regular and irregular square waves.

Key words: transient response, forced concentration oscillation, catalytic reaction, benzene
