Separation and Purification of Hydrogen Using CO2-Selective Facilitated Transport Membranes

Varun Vakharia; W. S. Winston Ho

A crucial step for the use of hydrogen as a clean, renewable source of energy towards a “hydrogen economy” is the purification of hydrogen from other gaseous compounds, mainly carbon dioxide and hydrogen sulfide. This chapter reviews the carbon dioxide- and hydrogen sulfide-selective facilitated transport membranes for low-pressure and high-pressure applications. Hydrophilic polymeric materials have been investigated that are blended with amino acid salts and polyamines as mobile and fixed-site CO2 carriers, respectively.
