Flue gas desulfurization (FGD) involves the removal of sulphur dioxide (SO2) contained in gases produced by the combustion of fossil fuels such as coal, oil, municipal solid waste and many industrial processes. In this context, the aim of our work was to investigate flue gas desulfurization using natural limestone reagents treated with mechano-chemical processes. In detail, we investigated the possibility of using high- energy (H/E) mills in the micronization phase of natural limestone instead of standard ones. Subsequently, the performance of micronized limestone into flue gas desulfurization was evaluated. Results highlighted how limestone obtained by H/E mills presented better performance than those from standard mill, with a greater amount of sulphates adsorbed during desulfurization tests. Furthermore, new investigations aimed at understanding the kinetics of the desulfurization process will be carried out in order to scale-up on industrial level.
