CATALYST SYSTEM, OXIDATION REACTOR CONTAINING THE SAME, AND PREPARATION METHOD FOR ACROLEIN AND ACRYLIC ACID USING THE SAME

摘要

The present invention relates to a catalyst system, an oxidation reactor containing the same, and a preparation method for acrolein and acrylic acid using the same. The use of the catalyst system according to the present invention allows effective prevention of heat accumulation in the catalyst layer during the preparation of acrolein and acrylic acid. Accordingly, deterioration of the catalyst can be avoided, and the catalyst can be used in a stable state over an extended period of time. Moreover, acrolein and acrylic acid can be prepared with high selectivity and in high yields.
