METHOD FOR SUPPORTING CATALYTIC METAL ON CATALYST CARRIER

Document Type and Number:

Japanese Patent JPH02222730

Kind Code:

A

Abstract:

PURPOSE: To uniformly support a catalytic metal on catalyst carriers in a short time by immersing the carriers in a soln. contg. the metal for a certain time, pulling up the carriers, making the concn. of the soln. uniform by bubbling and repeating these operations.

CONSTITUTION: Carriers 3 are put in a support frame 1 and this frame 1 is immersed in a soln. 4 contg. a catalytic metal in a soln. vessel 2. After the lapse of a certain time, the frame 1 is taken out of the soln. 4 and solenoid valves 7 are opened to introduce air from ducts 6. The soln. 4 is bubbled by the air and the concn. distribution of the soln. 4 is made uniform. The valves 7 are then closed and the frame 1 is lowered to immerse the carriers 3 in the soln. 4. These operations are repeated. The catalytic metal is uniformly supported in a short time.
