Description
Activated carbon powder has advantages such as fast filtration speed, good adsorption performance, strong decolorization and odor removal capability, and is economical and durable. It is widely used in industries including food, beverage, pharmaceuticals, drinking water, sugar, and oils and fats, as well as commonly applied in fields such as brewing, wastewater treatment, power plants, and electroplating. The dataset includes major raw and auxiliary materials, energy inputs, atmospheric emissions, and waste generated during production; infrastructure such as equipment manufacturing and plant construction are excluded from the system boundary. The life cycle inventory is compiled from data sourced from multiple references. Activated carbon powder is a by-product generated during sinter production.
Activity Description
The sintering process involves mixing raw materials such as iron ore fines, coke fines, and limestone, followed by sintering and cooling, ultimately forming a lumpy ore suitable for blast furnace smelting. Activated carbon fines are a by-product of this process.

Technology comment
Sintering in steel plants is a key preliminary process in steel production, primarily aimed at agglomerating iron ore fines or other raw materials into lump materials suitable for blast furnace smelting through high-temperature sintering. The main steps include raw material preparation, shaping, sintering, cooling, and treatment. During the sintering process, the raw materials are heated to high temperatures (typically between 1200°C and 1400°C). In this process, coke fines act as both a reductant and fuel, facilitating the melting and binding of ore particles into solid lumps under high temperatures.
