The Effect of Prewetting on the Loading of γ‐Alumina Washcoated Cordierite Monolith
Source abstract
Abstract
Washcoating of alumina on cordierite monoliths has been studied with the objective of preparing monoliths with high loadings (>30 wt%). As the alumina loading increased, the competition between spreading and imbibition of the slurry in the monolith channels had a predominant influence on the loading that could be achieved. It was observed that, partial saturation of the washcoat with water allowed the use of concentrated slurries during multiple immersions. The effect of prewetting on the washcoat properties such as adhesion, uniformity, porosity, and reproducibility was investigated.
