ABSTRACT:
A catalyst composition comprising palladium, silver and a support material (preferably alumina) is contacted with a liquid composition comprising an iodide component such as ammonium iodide, and the catalyst is then calcined. An improved process for hydrogenation, especially selectively hydrogenating acetylene (to ethylene), using this improved catalyst composition with improved conversion and deactivation.
