A SIMULATION STUDY ON THE THERMAL-DECOMPOSITION OF HYDROGEN-SULFIDE IN A MEMBRANE REACTOR

The thermal decomposition of hydrogen sulfide to produce hydrogen and sulfur was investigated in palladium and ceramic membrane reactors usi ng isothermal, one-dimensional models. The characteristic features of the reactors were evaluated in terms of dimensionless parameters relat ing the reaction coefficients, reactor geometry, membrane properties a nd operating conditions. The analysis of the results provided guidelin es to define the system boundaries, fix the design parameters and iden tify the areas of further developments.
