The coke cylinder was placed on the sample carrier for the gasification tests (see Fig. 2). The coke cylinders had a dimension of ∼15 mm D × 20 mm H, which translated into an initial weight in the range of 4.06–5.25 g depending on the coke type. Coke cylinders were first heated to 1100 °C under N 2. The mass loss of coke samples was ...

It is believed that a good quality metallurgical coke should have low CRI and high CSR. If the CRI is too high, the starting temperature of the reaction between the coke and CO 2 will decrease. In other words, the reaction may start at the upper part of the blast furnace, resulting in the generated CO escaping from the top of the blast furnace.
