Latest Patents

Ann Marie Hall holds 1 patent for her invention titled "Sulfur removal systems for protection of reforming catalysts." This process involves removing residual sulfur from hydrotreated naphtha feedstock. The feedstock is treated with molecular hydrogen under reforming conditions, utilizing a less sulfur-sensitive reforming catalyst. This method converts trace sulfur compounds into H₂S, resulting in a first effluent. The first effluent is then treated with a solid sulfur sorbent to eliminate H₂S, producing a second effluent. Finally, the second effluent is processed with a highly selective reforming catalyst under severe conditions. Additionally, her method incorporates a potassium-containing sulfur sorbent derived from nitrogen-free potassium compounds.
