Abstract
Methods for improving the sulfur-tolerance of nickel-based catalyst systems, as well as the improved catalyst systems, are disclosed. The methods can include adding praseodymium alone, or in combination with ruthenium and/or cerium, to a nickel-based catalyst system, thereby inhibiting sulfur poisoning of the catalyst system. Improved catalyst systems can have an added amount of praseodymium alone, or in combination with ruthenium and/or cerium, sufficient to inhibit poisoning of the system by sulfur.
Claims17
A method for improving sulfur tolerance in a hydrocarbon reforming and/or electrochemical catalyst system, the method characterized by adding praseodymium to the hydrocarbon reforming and/or electrochemical catalyst system, thereby inhibiting sulfur poisoning of the hydrocarbon reforming and/or electrochemical catalyst system.
