Novel platinum reforming catalysts and support materials.

摘要

A novel modified alumina support for reforming catalysts is provided. Also provided are reforming catalysts comprised of 0.01 to 2 wt.% platinum, 0 to 2 wt.% iridium, and 0 to 2 wt.% rhenium, on a modified alumina support which modifier is comprised of at least about 100 wppm Si and at least about 10 wppm of one or more alkaline earth metals selected from Ca, Mg, Ba, and Sr wherein the total amount of modifier does not exceed about 5,000 wppm.
