Sometimes it becomes. The filling work in this case is usually stored by a catalyst manufacturer in a large catalyst container such as a flexible container or a chemical drum, and the delivered granular catalyst is mixed with a liquid such as water in some cases. Transfer the small amount of the catalyst container to the catalyst container of the above, and lift the catalyst container with the crane to a position above the reactor at a high place, and align the discharge port of the catalyst container with the catalyst filling port of the reactor. The operation of opening the valve of the discharge port to allow the catalyst to flow into the reactor, and then lowering the empty catalyst container to the ground again with the crane is repeated.

Further, it takes a lot of time, and it is not unusual that several days are required when the catalyst amount of several tens m 3 or more is charged. Therefore, the development of a simple, safe and rapid filling method has been strongly desired.
