Abstract: Methods are provided for forming noble metal catalysts comprising both platinum and a second Group VIII metal, such as palladium, with improved aromatic saturation activity. Instead of impregnating a catalyst with both platinum and another Group VIII metal at the same time, a sequential impregnation can be used, with the Group VIII metal being impregnated prior to platinum. It has been discovered that by forming a Group VIII metal-impregnated catalyst first, and then impregnating with platinum, the distribution of platinum throughout the catalyst can be improved. The improved distribution of platinum can result in a catalyst with enhanced aromatic saturation activity relative to a catalyst with a similar composition formed by simultaneous impregnation.

Abstract: Catalyst compositions with improved alkylation activity and corresponding methods for making such catalyst compositions are provided. The catalyst(s) correspond to solid acid catalysts formed by exposing a catalyst precursor with a zeolitic framework structure to a molten metal salt that includes fluorine, such as a molten metal fluoride. The resulting fluorinated solid acid catalysts can have improved alkylation activity while having a reduced or minimized amount of structural change due to the exposure to the molten metal fluoride. This is in contrast to fluorinated solid acid catalysts that are exposed to higher severity forms of fluorination, such as exposure to ammonium fluoride or HF. SnF2 is an example of a suitable molten metal fluoride.

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.
