“…▪ The membrane module of the PBMR consists of tubular ceramic-supported carbon molecular sieve membranes (CMSMs), which show promising performance in terms of vapor/gas separation and stability in hot and humid environment, according to our previous work [48]. The properties of the membranes in terms of permeance of H 2 O, H 2 , CO 2 , CO and CH 3 OH as a function of temperature were determined experimentally and fitted with an Arrhenius law [49] (details in S.I.). DME permeance was assumed to be 50 times lower than that of H 2 O [50].…”
