Zusammenfassung:The invention relates to a composite material for the sea water desalinization and to a process for obtaining the same. According to the invention, the material is obtained by the impregnation of an activated carbonic material with organic hydrogel previously prepared by poly-condensing resorcinol with formaldehyde, afterwards the resulting composite is subjected to aging for 48 h at a temperature of 85°C, further on the water is removed, wherefrom there results a gel which is subjected to a thermal treatment at a temperature of 900...1000°C, the resulting composite material having an apparent density of 0.14...0.80 g/cm, a system of pores with sizes smaller than 2 nm and an electric resistance of 0.5...10 . Invenţia se referă la un material compozit pentru desalinizarea apei de mare, şi la un procedeu pentru obţinerea acestuia. Materialul conform invenţiei este obţinut prin impregnarea unui material carbonic activat cu hidrogel organic, preparat în prealabil prin policondensarea de rezorcinol cu formaldehidă, după care compozitul rezultat este supus îmbătrânirii timp de 48 h, la o temperatură de 85°C; în continuare este eliminată apa, din care rezultă un gel care este supus unui tratament termic la o temperatură de 900...1000°C, materialul compozit rezultat având o densitate aparentă de 0,14...0,80 g/cmc, un sistem de pori cu dimensiuni mai mici de 2 nm şi o rezistenţă electrică de 0,5...10 Ω .
