Adsorption of Carbon Dioxide to Polysaccharides in the Supercritical Region

Effect of a supercritical fluid on starch-based polymer processed with ionic liquid

“…A number of authors have shown that CO 2 can act as a plasticizer and induce mobility and interaction with the starch chains [26,[46][47][48][49].…”

Experimental and modeling studies on the solubility of sub‐ and supercritical carbon dioxide (scCO2) in potato starch and derivatives

“…Despite the importance of solubility data, experimentally determined solubilities of CO 2 in native starch samples for a wide range of conditions are limited. To the best of our knowledge, the work of Hoshino et al [15], Singh et al [16], and Chen and Rizvi [17] are the only articles concerning to the solubility of CO 2 in the starch. Hoshino et al [15] studied the adsorption of CO 2 in dried corn starch (water content of 3.8% wt/wt) at two different temperatures (40–50°C) and of dried potato starch (water content of 4.3% wt/wt) at a temperature of 40°C in a pressure range of 0–29.4 MPa by a gravimetric method.…”

The authors reported a decrease in the solubility with temperatures and observed a maximum solubility near the critical region of CO 2 followed by a sharp decrease at higher pressures [15].…”

The authors reported a decrease in the solubility with temperatures and observed a maximum solubility near the critical region of CO 2 followed by a sharp decrease at higher pressures [15]. Chen and Rizvi [17] measured the solubility of CO 2 in pregelatinized‐corn starch (water content of 40% wt/wt) at a temperature of 50°C and various pressures (up to 16 MPa) by a pressure decay method.…”

Improved manometric setup for the accurate determination of supercritical carbon dioxide sorption

“…A comprehensive overview on CO 2 storage in underground coal combined with the production of CH 4 is given by White et al 1 Experimental data of near supercritical CO 2 sorption on any type of material are scarce. A limited number of gravimetric, [2][3][4][5][6][7][8][9][10][11][12][13] manometric, 4,[14][15][16][17][18][19] and volumetric 20,21 studies have been published. Additional measurements are thus important.…”
