“…It is well-known that reactions (1) and (2) are very fast in the range of temperatures studied [27], while the reaction (3) is slow enough to be considered as the rate determining step for the hydrogen production through this thermochemical cycle [28]. This reaction sequence confirmed by experimental results is indicating that the kinetics of the Mark-15 Fe-Cl cycle has an important dependence with the system pressure.…”

“…The activation energy value over iron is noticeably smaller than that obtained for the chlorination of iron oxides: 105.2 kJ/mol over iron against 130 kJ/mol over iron oxides (Bertóti et al 1985). This result, as well as the reduced temperature of the reaction, supports the catalytic effect of metallic iron for the hydrolysis of chlorinated methane derivatives.…”

“…Carbon monoxide replaced CO 2 as the primary product formed by reaction of CCl 4 in nitrogen, although not entirely. The fact that, in the absence of oxygen, carbon monoxide was the primary reaction product suggests that the decomposition of chlorinated methane on iron due to hydrolysis proceeds mainly via formation of adsorbed CCl 2 -species (Bertóti et al 1985;Lara et al 1996), which then form carbon monoxide:…”

“…Mechanism of chlorination. [8,15,31], the subsequent reactions of Fe 3+ and Ti 4+ in the intermediate phases can be written as Eqs. (3) and (4) O ] IP + CCl 4 (g) → 2TiCl 4 (g) + CO 2 (g) (4) The reaction mechanism is shown in Fig.…”
