Emulsion-derived resorcinol-formaldehyde (RF) foams supplied by Sandia National Laboratories-California (SNL-California), have been successfully extracted at the Oak Ridge Y-12 Plant using supercritical carbon dioxide. One half of the resulting foams have been carbonized. Careful study of the extraction process has yielded a predictive model for supercritical extraction of thin RF foams and has resulted in the optimization of the extraction process. Extraction times and costs have been minimized. After the initial solvent exchange step, solvents were supercritically extracted from the RF gels in < 24 h at a cost of < $0.01 of CO[sub 2] per gram of solvent extracted.
