MULTI-FUNCTIONAL COATING AND NODEL OF COATING FOR THE CATALYTIC COATING OF 'WASHCOAT' AND / OR SOLUTION ON THE SUBSTRATE AND APPLICATION METHODS

摘要

The principles and embodiments of the present invention relate generally to an apparatus, system, and methods for coating and calcining a catalytic substrate inline, reducing the processing time to prepare a substrate coated with catalytic material. For example, the disclosure describes a multi-station coater system comprising: a raw weight station, wherein an initial weight of a substrate is measured; a first catalytic substrate coating station, wherein a first wet coating comprising a first catalytic coating and a first carrier liquid is introduced into longitudinal cells of the substrate; a first wet weight station, wherein a wet weight of the substrate is measured; a first inline calciner module, wherein a heating fluid is introduced into the substrate to calcine the catalytic coating; and a first calcined weight station, wherein a calcined weight of the substrate is measured.
