Designing activated carbons from natural and synthetic raw materials for pollut...
P.A.M. Mourão; I.P.P. Cansado; P.J.M. Carrott; M.M.L. Ribeiro CarrottOver the last decades the literature has shown the possibility of producing activated carbons (AC) from a wide variety of raw materials, and to use them as one of the most environmentfriendly solutions for waste disposal [1]. Simultaneously, it has been shown that the adsorption of pollutants from different sources by activated carbons is one of the most efficient techniques for remediating or solving this kind...
Hydrothermal stability of ordered mesoporous titanosilicate materials prepared ...
P.C. Galacho; M.M.L. Ribeiro Carrott; P.J.M. Carrott; I.P.P. CansadoA study of hydrothermal stability, performed in boiling water under static conditions, of MCM-41 materials containing different titanium content, prepared by direct synthesis at ambient temperature and pressure, using tetraethoxysilane, titanium ethoxide and octadecyltrimethylammonium bromide is presented. The behaviour is compared with pure silica grades prepared by a similar procedure. The samples were charac...
Activated Carbons Prepared from Natural and Synthetic Raw Materials with Potent...
I.P.P. Cansado; P.A.M. Mourão; M.M.L. Ribeiro Carrott; P.J.M. CarrottA carbon molecular sieve for the purification of a gas mixtures containing O2, N2 and CO2, CH4 was produced from a waste granulated PET by means of a single carbonisation step at 973 K. Activated carbon materials presenting good adsorption capacity and some selectivity for O2/N2 and CO2/CH4 were prepared from granulated PET and cork oak with pore mouth narrowing using CVD from benzene. The diffusion coefficient...
