Kinetics of H2S Decomposition in Plasma

As discussed earlier, the most effective plasma-chemical decomposition of hydrogen sulfide (10-58) occurs when the process starts with thermal decomposition (10-60) and is followed by sulfur clusterization (10-61) and product separation in a centrifugal field. Consider the kinetics of the process beginning with thermal decomposition (Potapkin et al., 1988). The elementary endothermic reaction initiating the total process (10-58) is the thermal dissociation of hydrogen sulfide  

Atomic hydrogen formed in the dissociation process then reacts with and decomposes another H2S molecule and forms molecular hydrogen in the fast exothermic process 

Active radical HS generated in reactions (10-63) and (10-64) react with each other and form molecular hydrogen and sulfur in the following fast exothermic reaction  

The HS radicals can also be converted into the prodncts H2 and S2 via the following sequence of two fast exothermic elementary reactions
