Abstract

The purpose of this work is a study on sulphur and potentially contaminant trace elements, present in fossil fuel, that are transferred to the environment through combustion. This study examines the performance of calcareous or dolomitic calcareous rocks as sorbents applied to SO] retention. In the combustion process were sulphur is present there is the formation of SO%, whose emission associated to photo-oxidation phenomena in the atmosphere generates SO], that under humidity conditions changes into sulphuric acid, that on its turn can react with metallic oxide of particulate material to generate sulphate. The air pollution from the burning of fossil fuels is the major cause of acid rain. Acidic deposition, or acid rain as it is commonly known, occurs when emissions of sulphur dioxide (SO]) react in the atmosphe
