PROCESS FOR PREPARING A PRE-REFORMING CATALYST HAVING RESISTANCE TO DEACTIVATION BY PASSAGE OF STEAM IN THE ABSENCE OF A REDUCING AGENT, AND A PRE-REFORMING CATALYST

摘要

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.
