- Summary:
- Metal hydride (MH) material can be used for effective separation of hydrogen from gas
mixture. However, some impurities in the feedstock gas may cause the poisoning of the
material and hence failure of the MH-based hydrogen separation system. In this paper, the
hydrogen storage alloy LaNi4.3Al0.7, which has low-plateau pressure and was supposed to
be used for hydrogen separation from the semi-coke oven gas, was tested in the atmosphere
with relatively high concentration of CO impurities (~0.1%v/v) by cycling experiments.
Interestingly, the hydrogen storage capacity of the material shows quite mild
decline during contact with CO at the temperature of 363 K or higher, and relatively fast
kinetics can be kept, highlighting its application potential for hydrogen separation on a
variety of occasions.
