The decomposition of thiophen, furane and pyrrole on molybdenum disulphide catalysts occurs by two-point adsorption, which leads to a half-hydrogenated state from which the hetero-atom is then broken off. Retardation is caused by molecules also capable of giving two-point adsorption. Tetrahydrothiophen and tetrahydrofurane are decomposed on the same catalysts, but the mechanism is probably simpler. On nickel subsulphide catalysts, the tetrahydro-derivatives are decomposed much more easily than the unhydrogenated molecules, and they are held by single-point adsorption on the 111-plane of Ni 3 S 2 on which pairs of hydrogen atoms are also adsorbed. Thiophen and furane decompose by reaction with metallic nickel produced by reduction of Ni 3 S 2 . The nickel sulphide or oxide thus formed are subsequently reconverted to metal. Retardation of these changes arises from any reactant which can compete for nickel atoms, or which can cover the subsulphide surface and prevent its conversion to metal.

Active Metal

The catalytic decomposition of hydroxylammonium nitrate (HAN) was investigated using a series of platinum and iridium supported on mesoporous materials. In this study, MMZY, KIT-6, and SBA-15 were used as supports. The effects of the active metal and the pore structure of the catalysts on decomposition of HAN solution were studied. The activity of the platinum catalysts supported on mesoporous material is much superior to that of the iridium catalysts on the same support. The Pt(10)/SBA-15 catalyst showed excellent decomposition activity and was the best among the catalysts tested here, which seemed to be because of the pore structure of Pt(10)/SBA-15. Because the pore size of Pt(10)/SBA-15 is larger than that of Pt(10)/MMZY and Pt(10)/KIT-6, it is more advantageous for diffusion of reactant and product gas. The activity of the catalyst increased as the amount of Pt loaded on the SBA-15 support increased.
