Monolithic catalyst-coated probes and their applications

Abstract

The invention relates to a monolithic catalyst coating probe, and in particular relates to an automobile honeycomb monolithic catalyst (ceramic and metal) coating probe. The monolithic catalyst coating probe comprises a probe part and a beam, wherein the diameter of the probe part is 0.1 to 20 micrometers approximately, and the diameter of the beam is 0.5 to 20 micrometers approximately. The monolithic catalyst coating probe can probe the coating height and position of a coating when a monolithic catalyst is coated sectionally on the basis that the catalyst is not subjected to breaking opening, ensures that the technical process is controllable, simultaneously avoids waste, and saves the cost.

Description

technical field [0001] The invention relates to a monolithic catalyst coating probe and its application, in particular to a motor vehicle honeycomb ceramic and metal monolithic catalyst coating probe and its application, as well as other monolithic industrial catalyst coating probes. Background technique [0002] The segmented coating process has been widely used in the matching and preparation of catalysts. The segmented coating enables the active components to be enriched in the front stage of the catalyst, which can reduce the light-off temperature of the catalyst in the cold start stage and improve the catalyst’s reaction to exhaust THC and CO. , NOx and other major pollutants purification efficiency. In the current preparation process, the segmental coating height and area are ignored, and there is no other good way to inspect it except breaking open the catalyst carrier, which will inevitably cause waste of the carrier. The invention of the probe can effectively solve...
