| Abstract Scope |
Petcoke slag is a petroleum byproduct originating from industrial processes such as gasification, which utilizes petcoke as carbon feedstock. Slag forms in the gasification reactor from ash impurities from the feedstock, most of which is currently dumped in landfill sites. The petcoke slag, however, commonly exhibits high concentrations of nickel and vanadium (as high as 6 wt.% and 20 wt.%, respectively), which are critical to many clean energy applications, including advanced batteries and high-performance alloys. In this work, segregation behavior of the nickel and vanadium from the petcoke slag was investigated under carbothermal conditions at up to 1,500 °C. Nickel tended to form either metallic nickel or carbide while vanadium formed vanadium oxide. Easy separation of those materials was achieved as the segregation occurred ‘above’ the slag surface. |
