APPARATUS FOR REMOVING SUBSTANCES FROM CATALYST SURFACE

摘要

Provided is an apparatus for efficiently removing substances (catalyst surface substances) exuding from and/or attached to a catalyst surface. An apparatus which is provided with a main body and which removes catalyst surface substances from the surface of a catalyst by bringing the catalyst stored in the main body into contact with airflow, wherein the length of the airflow in the airflow direction is 55 mm or greater, and the average flow velocity of the airflow is 80 m/s to 500 m/s when calculated as a linear velocity at 15°C and 1 atm.
