Procedure

Five different gel solutions were made by admixing a phenol and formaldehyde (molar ratio of phenol:formaldehyde=0.5:1) solution with a water/acid solvent. In some cases an ammonium acetate catalyst was added. The ratios of the various gel reagents are indicated in Table 21 for the five samples. The gel solution was allowed to mix for 5-10 minutes before it was poured into the cyclohexane/SPAN80 solution and the temperature was set to 95° C. and held for 3-5 days before the excess continuous phase was decanted. Wet gel samples were pyrolyzed directly at 625° C. for 1 hour with weight loss between 50-75%. Representative carbonization and activation data is presented in Table 22.
