Experimental study of the reaction of heterogeneous decomposition of the hydrogen sulfide on bulk oxides γ-Al 2 O 3 , α-Fe 2 O 3 and V 2 O 5 in the interval of temperatures 500-900 o C have been performed. Reaction orders by H 2 S for γ-Al 2 O 3 and V 2 O 5 are 2.0, and for α-Fe 2 O 3 - 2.6; effective activation energies are respectively 72, 94 and 103kJ/mol. Using the ESDR and XRD methods, it is shown that in the course of hydrogen sulfide decomposition reaction, the reduction of transition metal oxide catalysts (α-Fe 2 O 3 and V 2 O 5 ) and also the formation of sulfides under the influence of reaction media proceed. Interaction of hydrogen sulfide with aluminum oxide at low temperatures leads to formation of adsorbed species of H 2 S as fragments HS - and S 2 - , which upon heating 100-700 o C transfer into different species of sulfur: c-S 8 , c-S 1 2 , S 4 . In separate experiments it was demonstrated that the higher the temperature of H 2 S interaction with Al 2 O 3 , the larger number of adsorbed sulfur species are observed in the spectra. Molecular hydrogen sulfide interacts with the Al 2 O 3 surface with formation compounds of sulfur with oxygen, which later transform into the final reaction product - elemental sulfur.
