    摘要: A method for deciding the air reactivity, the CO2 reactivity and the soot index of carbon products, where the air reactivity and the CO2 reactivity of a sample of a carbon product are decided on the basis of the same test; the air reactivity is analysed first and, when this analysis is finished, the CO2 reactivity is automatically analysed on the same sample. The soot index is determined by collecting and weighing the soot dust. Equipment for carrying out the method, consisting of a vertical tube furnace (2) with an inlet (4) for the introduction of gas, and a sample holder (5) for the carbon product which is freely suspended from a weighing device (3) and reaches down into the tube furnace. The sample holder (5) is provided with one or more thermocouples for registering the temperature in the carbon product.
