摘要： A process wherein a regenerated, spent sulfided vanadium-containing Group VIII metal, Group VI-B metal, or Group VI-B/Group VIII metals containing catalyst is contacted with a stream of an oxygen-containing gas and the coke burned therefrom to regenerate the catalyst. The regenerated catalyst as such, or after reduction of the catalytic metals by contact with hydrogen, can be used as an adsorbent to remove essentially all of the sulfur from a naphtha feed which contains as much as 50 weight ppm sulfur, and greater.

摘要： A process for desensitizing a hypersensitive, high activity reforming catalyst for suppression of hydrogenolysis which is particularly acute during the early portion of the period that the catalyst is placed on stream, i.e., at the startup of a reactor. The catalyst is constituted of a composite which includes a Group VIII noble metal hydrogenation-dehydrogenation component, notably platinum, iridium, and selenium. Hydrogenolysis is suppressed by incorporating within such reforming catalyst at the time of its preparation an element, or a compound or salt of selenium. In another of its aspects the present invention embodies a reforming catalyst or catalyst composite comprising a refractory or inorganic oxide support material, particularly alumina, a Group VIII noble metal hydrogenation-dehydrogenation component, notably platinum, to which iridium, and selenium, have been added to promote the activity and selectivity of the catalysts, and said catalyst is prepared by a method wherein selenium is introduced into and deposited throughout said support. Suitably, the reforming catalyst, or composite also contains a halogen component, particularly chlorine and preferably the selenium component is introduced into the support, or catalyst, by impregnating with a solution comprising an element, salt, acid or compound of selenium.
