<p>The present invention relates to a catalyst system, an oxidation reactor comprising the same, and a method for producing an acrolein and an acrylic acid by using the same. By using the catalyst system according to the present invention, when acrolein and acrylic acid are produced, since heat accumulation in a catalyst layer may be effectively prevented, catalyst deterioration may be prevented, and the catalyst may be stably used for a long period of time. In addition, an acrolein and an acrylic acid may be produced at high selectivity and high yield.</p> |
