Unravel Stabilization Mechanism of CO2 Foams under High Temperature and High Pressure with HP-SANS
Abstract: Long-term stable CO2 foams were generated under high temperature (120 ºC) and high pressure (12 MPa) (HPHT) in our laboratory using a C22-tailed weak cationic surfactant, N-erucamidopropyl-N,N-dimethylamine (UC22AMPM), as the stabilizer. We hypothesize that the enhanced CO2 foam stability under HPHT was possibly attributed to the high bulk phase viscosity and interfacial viscosity resulted from the wormlike micelles (WLMs) formed from UC22AMPM molecules inside the wet foam film. Thus we request beam time of high-pressure small-angle neutron scattering (HP-SANS) to check the existence of such WLMs residing on the foam liquid channels under different temperature and different pressure.
