Graphitized Petroleum Coke(GPC)is a carbon-based additive commonly used in the casting and steelmaking processes. Graphitized Petroleum Coke (GPC) is produced by "graphitizing" high-quality petroleum coal. This process transforms the carbon amorphous in the coke to a highly organized crystalline graphite that can absorb and retain more heat. As a result, GPC can be used to reduce the amount of energy and scrap required in the casting process and increase the strength, hardness, and durability of the final product. The material also has outstanding qualities, including high electrical conductivity that can be used in lithium-ion batteries anodes.
GPC is a vital raw material in the production of metals and other industrial products, and its superior properties have contributed to its popularity among manufacturers worldwide. For example, the high electrical conductivity of GPC allows for rapid and efficient flow of electric current, minimizing resistance and power loss. This material also exhibits excellent thermal conductivity which allows for it to be resistant to high temperatures. GPC has unique properties that make it a vital component in modern industrial applications such as foundries, metallurgy or carbon product manufacturing.
As demand for sustainably produced materials grows, corporate responsibility standards are becoming increasingly stringent and regulatory policies are favoring low-carbon technologies by providing incentives or penalizing higher-emission activities. A global trend towards developing green steel has been sparked by this paradigm shift. In order to meet the demands of these targets and reduce greenhouse gases, businesses are using innovative and cost effective steelmaking techniques that lower emissions across the entire supply chain.
GHG emissions at different stages in the production of steel are significantly variable. The main concerns are direct emissions due to coal mining and energy usage at the input stage. Energy efficiency optimization, and use of renewable sources is crucial to reduce these direct emissions.
In the process of iron-and steelmaking, the primary source of emissions is fossil fuels used for iron reduction and coking in blast furnaces. The BF/BOF traditional process emits the largest amount of carbon dioxide per tonne steel. However, there are promising decarbonisation technologies that could potentially help to reduce these emissions.
Energy-intensive processes, such as hot and cold rolling, require large amounts electricity during the manufacturing of steel products. Adoption of renewable energy sources, optimization of processes and control and recovery methods of volatile organic compound (VOC) can all be used to reduce indirect emissions. Some companies have adopted circular economy concepts, using wastes rich in carbon, like plastics and wood waste, as a replacement for coal. It would reduce direct as well indirect emissions. This would not only reduce emissions, but also costs and waste.
