The production process of carbon molecular sieves with control morphology and microporous carbon molecular sieves

摘要

The production process of carbon molecular sieves with control morphology and microporous carbon molecular sieves. The present invention relates to a process for the production of molecular sieve carbon, which consists of a material carbonu00e1ceo microporous diameter of approximately 2nm, obtained from the technique of replication of a porous structure which serves as a mold.A series of molecular sieve carbon obtained by the object of the present invention process, known collectively as the family UEC, has several advantages when compared with molecular sieves as described in the literature, namely,The molecular sieves obtained in this invention have high values of pore volume and surface area; morphological feature unique and similar to those found in zeolites that have been used as molds for the production of the carbons have different groups Fu; Ncionais on the surface of its porous structure, high ratio (C / h,Which increases as the temperature of pyrolysis. The presence of said functional groups is controlled by the temperature of pyrolysis and the C / H ratio is directly proportional to the temperature.
