CHARACTERIZATION OF THE FUNCTIONAL CHEMICAL STRUCTURE OF SULPHUR IN POLYAROMATIC COMPOUNDS FROM HEAVYPETROLEUM FRACTIONS

摘要

The study of the determination of the functional chemical structure of sulphur in petroleum fractions is important due to its economical and environmental impact.The sulphurous compounds are responsible for the corrosive character and poisoning of catalysts in the transformation processes of petroleum products.In this way,sulphur compounds generate an economical impact on petroleum that extends to the storage,processing,transport and most importantly,to the quality of the final product.The combustion of petroleum products promotes the oxidation of sulphur compounds,generating polluting atmospheric gases of SO_x,which in contact with water produces sulphurous and sulphuric acids that contribute to the formation of acid rain,causing serious environmental pollution.
