Use advice for data set | Users of this data set should account for the energy and emissions associated with the coking process when conducting a Life Cycle Assessment for products where coke is used as a raw material. It is important to consider the specific chemistry and efficiency of the coking operation represented in this data set. Additional attention should be given to potential environmental impacts from by-products such as coal tar, ammonia, and sulfur compounds. Users should also ensure that the geographical relevance and technological applicability align with the scope of their assessment. |
Technical purpose of product or process | The coke produced in this industrial process is primarily used as a fuel and a reducing agent in blast furnaces during the production of iron and steel. It may also serve as a source of carbon for various chemical synthesis processes. |
