Abstract:
The paper presents research results on the pore structure and the reactivity of semicoke derived from LF, LFG, G, F, and C coal by low-temperature pyrolysis at 600 °C in the Fisher vessel. It is certified that the development of pore structure upon semi coking depends on the nature of the initial raw materials because when the degree of metamorphism is increased, the specific surface area of semicoke derived therefrom is reduced. As demonstrated by comparative analysis, semicoke derived using coal of a higher degree of metamorphism is characterised by reduced reactivity towards oxygen. The correlation between the temperature of the beginning of mass loss (T1) and that of maximum mass loss rate (Tmax) of oxidative breakdown for the investigated samples of semicoke vs its specific surface area was found. It is stated that T1 and Tmax indicators are reduced when the specific surface area of semicoke increases.
