A method for reforming naphtha feeds which comprises contacting said feed, in the presence of hydrogen and at reforming conditions, with a catalyst comprised of platinum and iridium agglomerated to exhibit a crystallinity of at least 50% as measured by X-ray, and an alumina support material modified

A method for reforming naphtha feeds which comprises contacting said feed, in the presence of hydrogen and at reforming conditions, with a catalyst comprised of platinum and iridium agglomerated to exhibit a crystallinity of at least 50% as measured by X-ray, and an alumina support material modified with at least about 100 wppm of Si and at least 10 wppm and one or more alkaline earth metals selected from Ca, Mg, Ba, and Sr, wherein the total amount of modifier does not exceed about 5000 wppm.
