“…These results are discussed by considering three regimens: (i) low TOS, lower than 2 h, when the sorption capacity of the zeolite is maximum, (ii) TOS around 2-4 h, when the zeolite has lost part of its capacity, but still absorbs H 2 O, and (iii) TOS higher than 4 h, when the zeolite is fully saturated and the stationary state has been reached (this regime is akin to the experiments conducted with the double catalytic bed without H 2 O removal shown above). Please note that, based on recent isotherm measurements [30], a capacity of 0.1 mmol/g may be expected under these conditions leading to a breakthrough time of around 4 h.…”
