Influence of nickel foam on kinetics and separation efficiency of hydrate-based Carbon dioxide separation

Hydrate-based Carbon dioxide (CO2) separation was widely concerned because of its simple process and low energy consumption. Mechanical stirring could promote gas-liquid-hydrate three-phase contact hydrate formation but consumed lots energy. Therefore, it necessary to develop more efficient technologies. Nickel foam (Ni–F) is an excellent hydrogen (H2) storage material with properties porous structure good thermal conductivity which are helpful heat mass transfer. In this work, by comparing the rate gas consumption CO2 efficiency, influence Ni–F on hydrate-based systematically studied. The results showed, firstly, both efficiency were increased using instead mechanical agitation; secondly, firstly found clear peaks corresponding H2 in Raman spectra hydrates formed presence under presure >4.00 MPa 273.85 K, indicated that stability hydrate. not only significant for further development hydate-based process, also provided a possible research direction storage.
