MOLECULAR SIEVE CARBON AND ITS PRODUCTION

摘要

PURPOSE: To obtain high-quality molecular sieve carbon having uniform pore diameters. CONSTITUTION: A heated and pressurized molded article of a pulp fiber material containing a phenol resin is carbonized to give molecular sieve carbon having a whole pore volume of >=0.2ml/g, a ratio of ultramicro pore volume having <=10Å to the whole pore volume of >=75% and the center of the pore diameter distribution in the range of 3-5Å.
