Oil Coke is the byproduct of crude refining and plays an essential role in multiple industries. The high carbon content of petroleum coke makes it a vital energy source for power generation, metalurgical applications and advanced materials. The production and usage of Petroleum Coke can have significant environmental impacts. Petroleum Coke can be used in innovative ways to reduce its environmental footprint as the world moves toward more sustainable energy.
Petcoke is a solid, dark by-product of petroleum refining. It is produced by heating heavy residuals from crude-oil refining in a controlled atmospheric. The vapors produced condense and become liquid, then solid. The solid form of green coke has a porous composition and high moisture level, making it unsuitable for many industrial uses. To make it more suitable, it goes through a process known as "coking", which removes impurities.
The resulting calcined petroleum coke has a low sulfur content, low nitrogen content, and low ash content. It is used in aluminum and steel smelting, as well as as a feedstock to synthesize graphite. The acicular nature of calcined oil coke gives it unique characteristics, such as high electrical conductivity, a low resistance and good chemical stability. This makes it an ideal material for use in the electrode industry.
The cofiring of petroleum coke and coal improves boiler efficiency and reduces particulate matter emissions and sulphur dioxides. A high-calorific-value fuel, petroleum coke can also be used to produce electricity. It is able to replace up 50% of the coal that would normally be used in a boiler. Note that flyash can become less efficient if the amount of unburned CO2 (UBC), a by-product of petroleum coke, increases.
Despite its negative impacts, petroleum coke is an important raw material in the global economy, and it has a wide variety of uses. It is hard and crumbly, which makes it easy to handle. It can also be used to generate energy at a low cost, in place of coal.
Petroleum coke is another key raw material used in the lithium batteries industry. The cheap alternative also has the ability to improve battery life and performance. Its acicular structure and high thermal conductivity provide superior mechanical properties, which make it the perfect choice for batteries. This is crucial for lithium-ion cells, as the structure of the battery must be rigid and maintain its shape. For this to happen, manufacturers need to ensure that the granules are of a high enough quality. This requires a combination of chemical and physical testing. The physical tests include measuring the density, resistance, and porosity of the granules. These measurements are important for determining the quality of the resulting graphite. Hiring a professional testing firm is essential.
