New kinetic data for the hydrogen sulfide decomposition reaction obtained from quartz tubular reactors over a temperature range of 800--1,250 C are reported. The study shows that the overall decomposition reaction has a first-order dependency on H{sub 2}S concentrations at these temperatures. The regression of experimental data gave an overall hydrogen sulfide decomposition reaction rate constant as k (m{sup 3}/kmol{center_dot}s) = (1.68 {+-} 0.86) {times} 10{sup 11} exp [({minus}28,940 {+-} 840)/T]. Moreover, for the first time, kinetic data from higher temperature (1,500--3,100 C) shock-tube studies and the lower temperature flow reactor study (this work) are reconciled. A single rate constant for H{sub 2}S decomposition reaction, k (m{sup 3}/kmol{center_dot}s) = (1.12 {+-} 0.11) {times} 10{sup 11} exp[{minus}(28,360 {+-} 200)/T] over a wide temperature range of 800--3,100 C was found to represent satisfactorily the three sets of data.
