A particularly attractive feedstock,?petroleum?coke (petcoke) is the solid carbon byproduct of the oil refining process. Asbury is a world-wide reliable source for both green and calcined petroleum coke (CPC) products. These high-quality, non-graphitic carbons can be found in applications ranging from foundry products and wear moderators for PTFE compounds, to reducing agents and drilling additives.
Green coke contains approximately 15-20% residual hydrocarbon materials, while?CPC offers a fixed carbon content between 97 and 99.5% and is virtually free of all residual hydrocarbons and moisture. Our experts are always on hand to help you select and source the right material for your needs and guarantee the quality of our product.
Commonly known as Met coke, Metallurgical coke is a high-quality, tough and resilient-wearing carbon with applications ranging from conductive flooring, ceramic packing media, friction and anti-corrosion materials, to foundry coating and carbon raisers. Manufactured through the destructive distillation of various blends of bituminous coal, where kilns are used to release volatile components including coal, tar, ammonia, and dozens of other products of decomposition, met coke is a non-melting carbon.
Typical purity varies between 88-92% fixed carbon, and commercial grades in sizes from 30-micron powders up to 20 centimeter lumps. Our team of experts will make it easy to source the right quality products and deliver seamlessly.
This low-sulfur solid carbon is the result of the thermal distillation of bituminous coal. Offering excellent thermal conductivity, pitch coke is inherently low in ash and other mineral impurities and is a highly graphitizable material with a range of potential uses.
Our expert teams will work with you to identify the right solution for your need, even determining if applications that call for calcined petroleum coke would benefit from pitch coke higher purity, low sulfur, and vanadium. Simply tell us about your need.
Calcined Needle Coke
This premium-grade, high value petroleum coke is used in a variety of applications, including the manufacture of graphite electrodes for electric arc furnaces in the steel industry. A highly crystalline form of carbon, it is typically higher in carbon and lower in ash constituents, such as sulfur and metals, than standard calcined petroleum coke.
It’s needle-like structure is the result of the high degree of liquid crystal alignment that occurs during the coking process. Needle coke offers unique friction and wear properties thanks to a well-developed layer structure. Applications where higher purity, softer calcined petroleum coke is required may also benefit from its use.
Our teams of experts are ready to help you identify the optimal option for your unique needs, then source it reliably through our extensive global network.
