Abstract: 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.

Abstract: Provided herein is a barium sulfate-containing catalyst carrier. The catalyst carrier is useful for supporting an exhaust gas purification catalyst, such as a three way conversion catalyst. In an embodiment, the carrier comprises BaSO4/thermally stable alumina. Further provided is a process for preparing the catalyst carrier, with or without precious metals, comprising treating a barium oxide/alumina or barium carbonate/alumina with a stoichiometric amount of sulfuric acid (H2SO4), thus forming BaSO4/alumina in situ in good yield and at low cost.
