“…Then, H 2 /toluene separation by various inorganic membranes has been widely studied. Kita and co-workers prepared an MFI membrane on the outer surface of tubular mullite support (Kumakiri et al, 2016). Their membrane showed the H 2 permeance of 1.6 × 10 -7 mol m -2 s -1 Pa -1 with the separation factor (H 2 /toluene) of 4.1 from the mixture of H 2 /toluene = 98/2.…”

Carbon molecular sieve (CMS) membranes were prepared on the outer surface of porous ceramic tubes using a lignin-based material, organosolvelignin, and a phenol resin, Bellpeal-S899, as precursors. Higher pyrolysis temperature resulted in higher hydrogen selectivity over oxygen or other larger gases, but hydrogen permeance decreased significantly. On the contrary, addition of a small amount of iron(III) acetate basic to the precursors improved the hydrogen selectivity but maintained the hydrogen permeance. Addition of iron compound to the precursor strongly reduced the permeances of nitrogen and methane through the resulting CMS membranes. Distribution of iron in the carbon matrix was evaluated by transmission electron microscopy energy dispersive X-ray spectroscopy (TEM-EDS) and electron probe microanalyzer (EPMA). The influence of aging on the membrane permeance was also studied. The results suggest the possibility to tune the size of ultra-micro-pores in CMS membranes using additives.

“…Recently, much research has been developing practical approaches for the realization of a hydrogen energy society. In order to realize a hydrogen energy society, various developments in areas such as fuel cells (Nakui, 2006;Ishitobi et al, 2016) and hydrogen permselective membranes (Sugiyama et al, 2015;Kumakiri et al, 2016;Miyamoto et al, 2017) are required. Efficient hydrogen production is an important technological development required for efficient energy utilization.…”

Thermochemical hydrogen production by the iodine-sulfur process decomposes water into hydrogen and oxygen by combining the chemical reactions of iodine (I) and sulfur (S). Two types of acids are produced through the Bunsen reaction (I 2 SO 2 H 2 O 2HI H 2 SO 4). To improve the performance of this reaction, ion-exchange membranes for the membrane Bunsen reaction should be developed. In the present study, a cation-exchange membrane was prepared using a radiation-graft polymerization method. It was found that a divinylbenzene crosslinking procedure was very e ective in reducing water permeation through the membrane, and the membrane Bunsen reaction was successfully carried out by using the developed crosslinked membrane. Moreover, sulfur deposition during the membrane Bunsen reaction was low for the crosslinked membrane. Therefore, the developed crosslinked membrane is a potential candidate as a cationexchange membrane for the membrane Bunsen reaction.
