Petroleum coke - Wikipedia

Calcined petroleum coke (CPC) is the product from calcining petroleum coke. This coke is the product of the coker unit in a crude oil refinery. The calcined petroleum coke is used to make anodes for the aluminium, steel and titanium smelting industry. The green coke must have sufficiently low metal content to be used as anode material.

Oligomerization of Fischer–Tropsch Tail Gas over H-ZSM-5

Fischer–Tropsch synthesis produces a product that invariably contains C4 and lighter material. The C2–C4 fraction has a high olefin content. The light hydrocarbons in the Fischer–Tropsch tail gas can be separated from the unconverted synthesis gas, but the added cost and complexity of doing so by pressure distillation is often considered unjustified. In this study the possibility of
