Plastics convert iron ore to steel Feedstock recycling in
Iron production takes place within a blast furnace. The reactor is about 30 to 40 metres high and includes a volume of up to 4.000 m3. Iron oxides and coke are conveyed from the top. The plastic waste is fed into the lower side of the blast furnace. The temperature in this part of the reactor reaches between 2.100°C and 2.300°C. Under these

Iron and Steel coke CarbonKit
Metallurgical coke is the solid product obtained from the carbonisation of coal (predominantly coking coal ) at high temperature and is used as a blast furnace feedstock in the production of iron and steel. As well as producing coke this process produces coke oven gas CO 2 CH 4 and other by-products.

A delayed coker is a type of coker whose process consists of heating a residual oil feed to its thermal cracking temperature in a furnace with multiple parallel passes. This cracks the heavy long chain hydrocarbon molecules of the residual oil into coker gas oil and petroleum coke.. Delayed coking is one of the unit processes used in many oil refineries.The adjacent photograph depicts a
