Deep decarbonisation of cement production News gasworld

In the case of ironmaking, carbon in the form of coke is used to draw oxygen out of the iron ore. Carbon dioxide (CO2) gas is the result. In cement making, calcium carbonate in the form of limestone is chemically reduced to form calcium oxide. Again, carbon dioxide is produced from the process chemistry. In the case of ironmaking, coke can be substituted with hydrogen as a reducing agent to
