“…Yang 6 investigated the conversion mechanism of thiophene into H 2 S, and claimed that the decomposition of thiophene tended to be triggered by hydrogen transfer between adjacent carbon atoms, and further hydrogen transfer and breakage of C–S bond led to the generation of H 2 S. Liu 7 discussed the effect of steam on the thiophene pyrolysis, and reported the conversion to H 2 S was promoted by steam, because the addition of steam catalyzed hydrogen transfer and saturated the thiophene ring. Similarly, Lu 8 studied the desulfurization mechanism of thiophene compounds in supercritical water, and found out that the introduction of H 2 O promoted the breakage of C-S bond, and thus promoting the generation of H 2 S. Zhang 9 compared the decomposition pathways of 2-methylthiophene during inert and oxidizing atmospheres, and reported that the desulfurization of 2-methylthiophene is thermodynamically more favorable in oxidizing atmosphere. Valuable conclusions have been obtained in published researches, H 2 evolution and its relationship with the released sulfur have also been studied 10 13 , while the re-fixation of H 2 S has also been investigated in previous research 14 ,the conversion mechanism of thiophene into H 2 S in different atmospheres have been elucidated.…”
