Effect of β-cyclodextrin on dissolution of methane in water

Methane was contacted with each solution in a cell and data of gas pressure vs. time and the total absorption capacity were collected. Addition of 0.5 wt% cyclodextrin increased the capacity of methane absorption as much as 14.63% at temperature 1 °C and primary pressure 3 bars, while the effect of its addition was reduced with temperature increase. Utilization of CD improved the pressure reduction slope of methane at low temperatures. Finally the graphs P-T-t at two initial pressures 3 and 5 bars were plotted for each solution.
