MONOLITH WASHCOAT AND METHOD OF DESIGNING |
摘要 |
<p>An optimum washcoated ceramic monolith for treating automotive exhaust gases is made by (a) specifying the reactants, process conditions and desired time on stream; (b) determining from the parameters in step (a) the pore size distribution and thickness of the washcoat to produce the desired auto exhaust conversion; (c) preparing a washcoat catalyst with an alumina having the desired pore size distribution; and (d) applying the prepared washcoat catalyst to a ceramic or metal monolith to produce a finished automotive exhaust gas catalyst. Following this process the optimized washcoated catalyst can then be used to treat automotive exhaust gases.</p> |
