Group VIII metals on manganese-containing oxide supports which exhibit strong metal support interactions

摘要

This invention relates to catalyst compositions comprising one or more Group VIII catalytic metals on a manganese-containing oxide support wherein the catalyst composition is contacted with a hydrogen-containing reducing atmosphere at elevated temperature to produce a catalyst composition which exhibits suppressed hydrogen chemisorption. The manganese-containing oxide may itself be supported on or mixed with inorganic refractory oxides prior to contacting the catalyst composition with the reducing atmosphere.
