Abstract
The present invention relates to a process for preparing a pre-reforming catalyst having resistance to deactivation by passage of steam in the absence of a reducing agent comprising ruthenium and an alumina support. Furthermore, the Ru/alumina catalyst according to the present invention becomes much more resistant to deposition of coke with the addition of Ag.
