Abstract: Procedimiento para la obtención de una espuma, constituida al menos por un 70 % en masa de carbono, mediante pirolisis de espumas de material sintético, caracterizado porque las espumas de material sintético, empleadas, contiene, al menos, un 30 % en masa de un material polímero con un contenido en nitrógeno por encima del 6 % en masa y tienen una porosidad comprendida entre el 35 % y el 99, 5 % así como una proporción de células abiertas mayor que el 1 %, que presentan productos inorgánicos incorporados y/o depositados sobre la superficie en la espuma de material sintético, elegidos del grupo formado por el cloruro de cinc, el carbonato de calcio, el polifosfato de amonio, el grafito expandido y los polvos metálicos y/o tratadas durante y/o después de la pirolisis con vapor de agua y/o con dióxido de carbono a temperaturas por encima de 400ºC.

Abstract: A foam (I) comprises at least 70 wt.% of carbon with an average cell size of over 20 microns, a porosity of 35-99.5% , over 90% open cells, an internal surface area of over 50 m2/g with cell crosspieces that have a triangular cross-section with inwardly curved sides and pores in the cell framework material of 0.2-50 nm in size and a volume of 0.01-0.8 cm3/g. Independent claims are included for: (1) a powder material (II) prepared by comminution of the foam (I) and; (2) a process for the production of the foam (I) by pyrolysis of a polymer foam, comprising at least 30 wt.% of a polymer material having a nitrogen content of greater than 6 wt.%, porosity of 35-99.5%, open cell content of less than 1% and inorganic materials processed into the foam or applied onto the surface whereby during and/or after pyrolysis the foam treated with water vapor, carbon dioxide and/or oxygen at over 400 degreesC.
