Employing phosphorylated betaines as kinetic hydrate promoters for gas storage application

Pursuing an effective promoter of gas hydrate formation remains a relevant issue in the potential development of solidified natural gas technology. The promoting ability of isopropyl [(N-alkyl-N,N-dimethylammonio)methyl]-phosphonate betaines was assessed using rocking cells equipment. The results reveal that the varying alkyl length makes it possible to accelerate either the nucleation or the growth of model natural gas hydrate.
