heal.abstract	A promising method for hydrogen production from the reaction of hydrogen sulphide and methane is studied. The equilibrium composition of the gaseous mixture CH4/H2S/H2/CS2/S2/C2H6/C2H4 is calculated over a temperature range of 973 to 1098 K under 0.1 MPa pressure. It is shown that at equilibrium state the gas mixture practically contains CH4, H2S, H2 and CS2 when the initial gas mixture contains 10-90% mole/mole hydrogen sulphide. Experiments were carried out in a thermal non-catalytic and in a MoS2 catalytic tubular reactor. A comparison of the experimental data is presented. It is shown that the catalytic reaction rates are much greater than the thermal ones. The catalyst is irreversibly deactivated but after 240 x 10(3) s in operation it reaches a level of constant, about 50%, remaining activity. An economic evaluation of the process is also presented.	en
