<P>PROBLEM TO BE SOLVED: To provide an activated ignition promoter for metal catalyzed reaction. <P>SOLUTION: The activated ignition promoters comprise one or more activated metals. The activated ignition promoters are easily prepared from a number of metal sources, including used catalysts, are quickly activated and provide effective catalytic ignition independent of the quality of the metals that comprise the catalytic converter. The one or more activated metals comprising the ignition promoter are prepared by contacting them with one or more kinds of chemical treatment. The activated metal components are prepared into suitable articles, referred to ignition strips, and are placed in contact with one or more oxidative coupling catalysts, typically in the form of gauzes. The ignition promoters reduce the activation energy for catalytic ignition (also referred to "light off") and permit the ignition of catalytic gauzes that are new, used, contaminated and damaged, and combinations thereof at a relatively low auto-ignition temperature. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
