Petroleum coke Wikipedia
Petroleum coke, abbreviated coke or petcoke, is a final carbonrich solid material that derives from oil refining, and is one type of the group of fuels referred to as cokesPetcoke is the coke that, in particular, derives from a final cracking process—a thermobased chemical engineering process that splits long chain hydrocarbons of petroleum into shorter chains—that takes place in unitsThis concentrated ore is then mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top It is in the blast furnace that extraction of iron occurs The extraction of iron from its ore is a very long and forlorn process that separates the usefulIron Ore Mining Techniques, Metal Extraction, Types of
Coking Wikipedia
Coking is the heating of coal in the absence of oxygen to a temperature above 600 °C, to drive off the volatile components of the raw coal, leaving a hard, strong, porous material of high carbon content, called cokeCoke consists almost entirely of hydrocarbonsThe porosity gives it a high surface area, which makes it burn faster (as does a sheet of paper versus a wooden log)The heat of the furnace decomposes the limestone to give calcium oxide \[ CaCO3 \rightarrow CaO + CO2 \tag{5}\] This is an endothermic reaction, absorbing heat from the furnace It is therefore important not to add too much limestone because it would otherwise cool the furnaceThe Extraction of Iron Chemistry LibreTexts
