heal.abstract	The kinetics of hydrogen sulfide decomposition on catalyst MoS2 is studied with the use of a tubular reactor. Data were obtained in the temperature range 1013-1133 K, pressure range 1.3-3.1 atm, and feed specific flow rate range 2.8 x 10(-4)-3.5 x 10(-3) mol/(s.cm2). A Hougen-Watson adsorption model is adopted to represent the reaction mechanism. Analysis of the data indicates that the rate-determining step of the decomposition reaction is the cleavage of hydrogen-sulfur bonds of the hydrogen sulfide adsorbed on the catalyst active sites. The kinetic parameters and their dependence on temperature are determined. The dependence of the catalyst irreversible deactivation on the reaction temperature is presented and discussed.	en
