Abstract

Sulfur-tolerant reforming catalysts that include bulk alumina in the catalyst support are provided. The sulfur-tolerant reforming catalysts can include a sulfur-tolerant catalytic metal to facilitate reforming. The catalyst can further include a support material that includes at least some alumina as bulk alumina and/or octahedrally coordinated alumina. The sulfur-tolerant reforming catalysts can be regenerated, such as periodically regenerated, under relatively mild conditions that allow the catalysts to maintain reforming activity in the presence of 1 vppm to 1000 vppm of sulfur in the feed for reforming.
