Stricter requirements for sulfur content in motor fuels stimulates the search for new ways of purification of hydrocarbons from sulfur containing compounds as well as improvement of existing technologies of desulphurization processes. In this paper, we propose a new approach to demercaptanization of hydrocarbon fuels based on the use of homo- and heteronuclear carboxylate complexes of transition metals deposited on heterogeneous substrates. Quantum chemical calculations on the decomposition process of methyl mercaptan by pivalates of d-elements (Co, Cu, Ni, Fe), adsorbed on a heterogeneous substrate (aluminum oxide) were carried out to determine the d-element corresponding to the most efficient catalyst.
