One of new perspective method for diesel fuels desulfurization is selective oxidation of their sulfur-containing compounds over catalysts with oxygen (ODS). Therein during this process the sulfide and heterocyclic sulfur-compound are transformed to sulfur dioxide, and the hydrocarbon fragment is oxidized to carbon dioxide and water. According to the literature CuZnAl-O catalysts can be promising for ODS. The goal of this work is to study sulfur adsorption capacity of CuZnAl-O in a model (dibenzothiophene in toluene) and a straight-run diesel fuel. It has been shown that CuZnAl-O catalysts actually possess sorption capacity. The trend of an increase of the sorption capacity with respect to sulfur at the transition from DBT derivatives to simpler sulfur containing molecules has been observed. DTA-TG-MS analysis has shown that the sulfur on the catalyst surface is represented by sulfides/polysulfides and sulfate of metals. Carbon deposits on the surface are products of the hydrocarbon condensation.
