Title:
CATALYST FILLING METHOD
Document Type and Number:
Japanese Patent JP2004195279
Kind Code:
A
Abstract:
To fill a fixed bed multi-tube type reactor with a catalyst while minimizing the powdering and collapse of the catalyst at the time of filling without exerting influence on a catalyst filling work time when the reaction tubes of the reactor are filled with the catalyst.
In this catalyst filling method, the reaction tubes of the fixed bed multi-tube type reactor are filled with the catalyst in such a state that a chain-like substance is inserted into each of the reaction tubes so that the lower end thereof is located at a position above the upper end of a catalyst bed.
