The inventive catalyst consists of silver crystals which are in contact with the phases of a mixed MgO, CeO 2 and Al 2 O 3 medium. The Ag\/MgO-CeO 2 -Al 2 O 3 catalyst can be used to obtain NO conversion levels which are greater than 40 %, nitrogen selectivity values of greater than 95 % and CO 2 selectivity values greater than 97% under NO x oxidation conditions in the 150-400 DEG C temperature range and for a surface contact time of 0.09 s. In particular, 90% NO conversion is obtained as well as N 2 and CO 2 selectivity levels of 99 % at 250 DEG C with a reaction mixture of 500 ppm NO\/1000 ppm C 2 H 5 OH \/5% O 2 \/5% H 2 O \/ 50ppm SO 2 \/He.<\/p>\n<p>Link:\u00a0<a href=\"http:\/\/goo.gl\/Uva3Qg\">http:\/\/goo.gl\/Uva3Qg<\/a><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The invention relates to a novel catalyst having excellent activity, selectivity and stability for reducing nitric oxide to gas nitrogen, with ethanol or an ethanol-hydrogen mixture being used as a&hellip; <a href=\"http:\/\/intentip.cut.ac.cy\/EL\/2015\/10\/26\/catalyst-for-the-reduction-of-no-to-n2-with-ethanol-or-ethanol-and-hydrogen-under-lean-denox-conditions\/\">Continue reading&#8230;<\/a><\/p>\n","protected":false},"author":59,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-169","post","type-post","status-publish","format-standard","hentry","category-uncategorized"],"_links":{"self":[{"href":"http:\/\/intentip.cut.ac.cy\/EL\/wp-json\/wp\/v2\/posts\/169","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/intentip.cut.ac.cy\/EL\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/intentip.cut.ac.cy\/EL\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/intentip.cut.ac.cy\/EL\/wp-json\/wp\/v2\/users\/59"}],"replies":[{"embeddable":true,"href":"http:\/\/intentip.cut.ac.cy\/EL\/wp-json\/wp\/v2\/comments?post=169"}],"version-history":[{"count":1,"href":"http:\/\/intentip.cut.ac.cy\/EL\/wp-json\/wp\/v2\/posts\/169\/revisions"}],"predecessor-version":[{"id":170,"href":"http:\/\/intentip.cut.ac.cy\/EL\/wp-json\/wp\/v2\/posts\/169\/revisions\/170"}],"wp:attachment":[{"href":"http:\/\/intentip.cut.ac.cy\/EL\/wp-json\/wp\/v2\/media?parent=169"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/intentip.cut.ac.cy\/EL\/wp-json\/wp\/v2\/categories?post=169"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/intentip.cut.ac.cy\/EL\/wp-json\/wp\/v2\/tags?post=169"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
