摘要：

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 degrees C 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.
