A combination process of chemical reaction and physical extraction was carried out in the investigation of. Peroxyacids prepared with hydrogen peroxide and acetic acid was used as oxidation reagents, with which sulfur-containing compounds in diesel could be converted to the corresponding sulfates. Dim ethyl sulfoxide (DMSO) is an effective solvent for extracting such sulfates from diesel, so the sulfur was removed. We studied the operating parameters of oxidation and extraction, such as the quantity of the ...
