N2 - Rapid formation of paste-like hydrate composite was investigated as an alternative to pure CO 2 hydrate formation for ocean sequestration of CO 2. The formation of a sinking CO 2 hydrate/liquid CO 2/H 2O composite in a co-flow injector reactor in pressurized vessels was examined, both at pressure and temperature equivalent to ocean depth of ∼ 1.3 km. Shifts in frequency corresponding to the CO 2 and water molecules as well as different phases of CO 2 in the composite were obtained. The Raman spectrum of CO 2 was characterized by the C-O-bend and C-O-stretch at ∼ 1281 and ∼ 1384 Ä/cm, respectively while the Raman spectrum of water was characterized by the O-H bend and stretch at ∼ 1645 and ∼ 3426 Ä/cm, respectively. This is an abstract of a paper presented at the 228th ACS National Meeting (Philadelphia, PA 8/22-26/2004).
