Abstract
Quantum molecular sieving separability of D<sub>2</sub> from an
H<sub>2</sub>–D<sub>2</sub> mixture was measured at 77 K for
activated carbon fiber, carbon molecular sieve, zeolite and single
wall carbon nanotube using a flow method. The amount of adsorbed D<sub>2</sub> was evidently larger than H<sub>2</sub> for all samples.
The maximum adsorption ratio difference between D<sub>2</sub> and
H<sub>2</sub> was 40% for zeolite (MS13X), yielding a selectivity
for D<sub>2</sub> with respect to H<sub>2</sub> of 3.05
