<p>[QUOTE=&quot;desertgem, post: 991189, member: 15199&quot;]If it is a true catalyst, the reaction would only use the silver as a surface for the formation of ethylene oxide. But we know how reactive silver is in gases such as oxygen, so probably the &quot;silver dust&quot;&nbsp; and the reason the silver coated ceramic &quot;carrier&quot; needs to be reclaimed is silver&#039;s reaction with other than the ethylene. I would suspect the reclaiming rate would be very high. Swagger1, do you know if the reclamation just returns the silver to its original state on the ceramic, or if the silver is removed from the ceramic and reintroduced onto new ceramic. I would think that reacting it with hydrogen gas or such might reverse the reaction, but that might not be so, as they would probably have developed a process to do it in your ethylene oxide reactor by back flushing hydrogen through it. Thanks for the nice post. ethylene oxide blows up badly. Use to use it in autoclaving, but mixed it with inert gas&nbsp; <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" /></p><p><br /></p><p>This may not be the patent on your material, but it reads close on the silver/ceramics catalyst.</p><p><br /></p><p><a href="http://www.freepatentsonline.com/5734068.html" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.freepatentsonline.com/5734068.html" rel="nofollow">http://www.freepatentsonline.com/5734068.html</a></p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
