Description
Petroleum coke can be used in the production of carbon, electrodes, refractory materials, as well as in aluminum electrolysis and aluminum products, and as an electrode binder. This dataset includes primary raw materials, auxiliary materials, energy inputs, atmospheric emissions, and waste from the production process; however, infrastructure such as production equipment and facility construction are excluded from the system boundary. The life cycle inventory is compiled from data sourced from multiple references. The manufacturing process for graphite electrodes includes operations such as mixing and forming, baking, impregnation, re-baking, graphitization, and machining, with petroleum coke being a by-product of this process.
Activity Description
The production activities of this product include processes such as mixing and molding, firing, impregnation, re-firing, graphitization, and machining; asphalt coke is a byproduct of this process.
Process Description
Petroleum pitch coke is a low-sulfur, low-ash coke, typically produced by direct coking of coal tar pitch in a coking furnace, or alternatively manufactured via delayed coking, with a final coking temperature above 1100°C. The molecular formula of petroleum pitch coke can be represented as CxHy, where x and y vary depending on the specific chemical structure; however, during the coking process, the hydrogen content generally decreases and the carbon structure becomes more ordered. At the consumer level, petroleum pitch coke is primarily used in the following applications: 1. The electrochemical industry, as a raw material for electrodes in aluminum smelting, usually mixed with coal tar pitch and formed into blocks for use as electrode substrates; 2. The production of advanced cast iron, such as ductile cast iron. In industrial applications, this material is used to manufacture products in the following industries: 1. Carbon plants, for producing prebaked anodes, carbon blocks, graphite electrodes, electrode paste, anode paste, sealant paste, electrode materials, high-power electrode rods, cold ramming paste, ferrous metallurgy carbon products, carbon brushes, electric arc furnace steelmaking electrodes, etc.; 2. Refractory plants, primarily for manufacturing blast furnace gunning paste, waterless gunning mud, furnace repair materials, blast furnace ramming mixes, blast furnace castables, unshaped refractories, magnesia-carbon bricks, carbon enhancers, refractory binders, high-temperature solid lubricants, etc.; 3. Electrolytic aluminum plant, mainly used for producing electrolytic aluminum, aluminum products, and as an electrode binder.
