Microporous carbons were prepared from Novoiac resin acti\ cited in the reaction with solid NaOH . The effects of activation temperature and time and the NaOH/resin ratio on the porosity were studied. It was shown that the changes in the reaction temperature (within 600-800°C) and reaction time had no significant effect on the porosity whereas NaOH/resin ratio had strong effect on the porosity. The ratio of 2:1 appeared to be the most appropriate for obtaining highly porous carbons. The influence of HMTAused for Novoiac curing on the yield and the characteristics of activated carbon was also investigated. The curing before activation increased the yield of final product without decreasing its porosity.
