Patent number: 8709967Abstract: A wire catalyst for hydrogenation reaction and/or dehydrogenation reaction comprises a metallic core and an oxide surface layer covering at least part of the surface thereof. The metallic core is electrically conductive so that the metallic core itself can generate heat by directly passing an electric current therethrough or electromagnetic induction. The oxide surface layer is made of an oxide of a metallic element constituting the metallic core. The oxide surface layer is provided with a porous structure having pores opening at the surface of the oxide surface layer. The catalytic material is supported in the pores of the oxide surface layer. When a shaped wire catalyst is manufactured, the shaping into a specific shape is made before the oxide surface layer having the porous structure is formed and the catalytic material is supported thereon.Type: GrantFiled: April 27, 2011Date of Patent: April 29, 2014Assignees: Nippon Seisen Co., Ltd.Inventors: Masaru Ichikawa, Yoshinori Tanimoto, Tsuneo Akiura

Patent number: 8702973Abstract: One exemplary embodiment can be a process for upgrading one or more hydrocarbons boiling in a naphtha range including less than about 5%, by weight, one or more alkenes and about 2,000-about 5,000 wppm, S, comprised in one or more sulfur-containing compounds, based on the weight of the one or more hydrocarbons. The process can include contacting the one or more hydrocarbons with a catalyst. The catalyst may include about 0.1-about 10%, by weight, NiO, about 5-about 50%, by weight, MoO3, and about 0.1-about 10%, by weight, P, with the balance of the catalyst comprising Al2O3. The process can obtain an upgraded one or more hydrocarbons having a thiol concentration of no more than about 20 wppm, S, based on the sulfur comprised in one or more thiol compounds divided by the weight of the upgraded one or more hydrocarbons.Type: GrantFiled: March 15, 2011Date of Patent: April 22, 2014Assignee: UOP LLCInventors: Colleen Costello, Suheil F. Abdo, Keith Adrian Holder, Ashley James Austin, Willie J. Morrissette, Jr.
