Continuous System For Providing A Catalytic Coating On Support Members
view source
US Patent:

40668010, Jan 3, 1978
Filed:

Dec 15, 1975
Appl. No.:

5/641118
Inventors:

William A. Hoyer - Evanston IL
Lowell W. Johnson - Kildeer IL
Richard J. Schoenenberger - Kildeer IL
Assignee:

Universal Oil Products Company - Des Plaines IL
International Classification:

B01J 3702
US Classification:

427 8
Abstract:

A processing system which can provide a continuous assembly-line procedure for placing a catalytic coating on ceramic honeycomb type members embodies the use of a plurality of pressure tight chambers such that each ceramic member can be vacuum treated and then rapidly coated, as well as pressure treated and air blown to effect rapid coating fluid removal and partial drying. After each coating operation, there is controlled drying and high temperature curing. Also, in a preferred controlled system, there is a weighing of each element before and after each coating step to determine an amount of coating retained for comparison with a predetermined standard.

US Patent:

Filed:

Sep 25, 1975
Appl. No.:

5/616750
Inventors:

William A. Hoyer - Evanston IL
Lowell W. Johnson - Fox Lake IL
Assignee:

Universal Oil Products Company - Des Plaines IL
International Classification:

B01J 2104
B01J 2340
B01J 3504
US Classification:

252466PT
Abstract:

A liftable housing form of pressure tight treating chamber is especially adapted to providing multiple stage treatments to catalyst support members, such as honeycomb-type elements, in order to place a catalytic coating on all of the interior surfaces of the multiple passageways through the elements. Power operated lifting of an open-bottomed housing permits the placement of members on sharp edged pin support means in the interior of the chamber such that passageways will not be blocked while the element is being subjected to vacuum, liquid coating, and air blowing stages.
