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.

Abstract: A reforming catalyst with improved surface area is provided by using high surface area alumina doped with a stabilizer metal as a catalyst support. The surface area of the catalyst can be higher than a typical reforming catalyst, and the surface area can also be maintained under high temperature operation. This can allow use of the catalyst for reforming in a higher temperature environment while maintaining a higher surface area, which can allow for improved dispersion and/or activity of an active metal such as rhodium on the catalyst support. The catalyst can be suitable for production of syngas from natural gas or other hydrocarbon-containing feeds.
