ALVAREZ MORENO, ANDREA; MORENO GUAQUETA, SONIA y MOLINA GALLEGO, RAFAEL. EFFECT OF AGGREGATE CLAY SIZE IN THE PHENOL OXIDATION IN DILUTED AQUEOUS MEDIUM. Dyna rev.fac.nac.minas [online]. 2010, vol.77, n.162, pp.57-66. ISSN 0012-7353.
This work presents a study about the effect of the aggregate clay size in the pillaring process, employing an Al-Ce-Fe polymeric precursor in concentrated clay suspension. Two smectite colombian clays were chosen (Bentonite and M64) and aggregate sizes ≤2mm, ≤50mm and ≤150mm were separated. The results show the success in the modification for all the solids with no importance of the aggregate size of clay used. The catalytic tests in the phenol oxidation in diluted aqueous phase show, in all cases, 100% of phenol conversion after 2h and total organic carbon (TOC) elimination between 50 and 58% in 4h of reaction.
