Experimental study on the kinetic effect of N-butyl-N-methylpyrrolidinium bromide on CO2 hydrate
The kinetic effects of N-butyl-N-methylpyrrolidinium bromide ([Py14]-Br) on the formation of CO2 gas hydrates were experimentally investigated. Both of the induction time of CO2 hydrates formation and the formation rates were investigated in the aqueous solutions of [Py14]-Br at different concentrat...
