It is not hydrogen, but after reacting a thiol with a ketone, this element can be used to reduce the thioacetal to an alkane in the Mozingo reaction. Sodium sulfate and coal can be used to refine this element in the Oxford process. This element is found alongside iron and sulfur in the ore pentlandite. This element is synthesized by reacting its oxide with Syngas to form its tetracarbonyl, which then decomposes into this element's pure form at high temperature. This element can be found in a catalyst that can fully reduce benzene to cyclohexane. That catalyst is an alloy of this element and aluminum and is named for Raney. For 10 points, name this transition metal synthesized in the Mond process, most commonly produced in Sudbury, Ontario.
