Kinetic and Mechanism of Oxidation of Hydrogen Sulfide Over Fe/SiO2 Catalyst

Abstract

The hydrogen sulfide oxidation kinetics for sulphur production over Fe/SiO₂ catalyst was studied in a cylindrical fixed bed reactor at 0.9 atmospheric pressure and 200-270 ºC temperature range was used. Results show that hydrogen sulfide reacts over catalyst through two separately pathway. It is believed that the sulphur formation from hydrogen sulfide, take place in a reversible pathway. Kinetic conclusion and subsequently the reaction mechanism, was performed upon experimental measurements of reaction product concentration values.
