Abstract
A process for the methanation of carbon monoxide and/or carbon dioxide in a feed stream containing carbon monoxide and/or carbon dioxide is disclosed. This is achieved by a process for the methanation of carbon monoxide and/or carbon dioxide in a feed stream containing carbon monoxide and/or carbon dioxide, hydrogen and more than 1 ppb of sulfur, using a catalyst comprising aluminum oxide, an Ni active composition and Mn. It has surprisingly The Mn-containing Ni catalyst has a high sulfur resistance and also a high sulfur capacity.
