The petroleum coke produced by oil refining is a carbon-rich product. It has many uses, depending upon its quality and properties. It can be produced as carbon electrodes for the aluminum smelting process, as fuel for power plants, or as a carbon source for steelmaking. It can be used to make graphite, and carbon-based items. In the steelmaking sector, low sulfur graphite oil coke (GPC), which is suitable for smelting, is especially desirable.
GPC can be obtained in a number of forms, depending upon the refining process and the desired quality. The lowest-quality petroleum is sponge coke. It is produced from vacuum residues left over after Crude Oil Distillation. It is highly impure and has a sponge like structure. It is used as a raw material for calcination, which transforms it into a more stable form known as calcined petroleum coke (CPC).
Fluid Catalytic Cracker decant oils are used as a feedstock to produce higher-quality Petcoke. It is less crystallized and has a honeycomb structure. This coke is of moderate value and used to make electrodes for the aluminum and steel industries. Needle coke has a needle like structure and it is resistant to breaking. It is produced by delayed kilning of high quality aromatic feeds. It is the coke of choice for manufacturing graphite electrodes in the aluminum and steel industries.
Graphite Petroleum Coke is also used as an intermediate product in the production of carbon and graphite-based products. It is a versatile and unique raw material. It has excellent thermal conductivity, as well as a high specific area. Graphite petroleum is available in a large range of sizes. This allows manufacturers to select the right particle size or shape for each application. The Graphite Petroleum Coke has a variety of other uses, such as supplying high quality carbon for special steel-making and casting processes and manufacturing conductive filler for ground electrodes in the aluminum industry.
Sulfurgraphite Coke is a preferred choice in the aluminum industry as it provides the best carbon source to melt alumina. It also offers several advantages over alternative coal-based carbon sources, such as charcoal.
DYM Resources is a leader in the supply of specialty cokes including Needle Coke. These advanced carbon material are designed to meet industry's exacting requirements. They are manufactured using a two-step centrifuging process, in which the unreacted larger particles were sedimented and discarded while the supernatant was collected.
Graphite Petroleum Coke is an essential building block in the aluminum supply chain, serving as a critical "carbon link" between refineries and aluminum producers. Rain Carbon's metallurgical knowledge and global supply network ensure that customers receive the highest-quality CPC for smelting or casting operations. This ensures the production systems are running at maximum efficiency. Our specialized technology allows us a variety of CPC grades to ensure that our customers get exactly what they want.
