Title: Catalyst combination method
Inventor: BAEK UN SEOK
IPC: F01N3/20
Filed: 2002-06-25
Abstract: PURPOSE: A catalyst combining method is provided to prevent crack of a catalyst, and to improve the durability of the catalyst by restricting pressure from being applied to the catalyst in inserting the catalyst with contacting to the catalyst in expanding the supporter. CONSTITUTION: The diameter of a catalyst is measured, and a guide is set corresponding to the catalyst. The guide is wound by a supporter to support the catalyst, and inserted to a ternary catalyst case with powerful pressure. The catalyst is pushed into the guide, and the guide is removed. The catalyst is supported by expanding the supporter. The guide is separated from the catalyst after fitting the catalyst into the guide. The supporter is expanded and contacted to the catalyst in drawing the guide out. Breakage of the catalyst is prevented by restricting overpressure to the catalyst in mounting the catalyst in the case.
