Resumo: | Montmorillonite clay from Brazil was pillared with aluminium polyhydroxications. The influence of Al/Mont ratio and calcination temperature in the properties of the prepared materials was studied. Results showed that the pillarization process increases the basal spaces of the natural clay from 9,7 to 18,5Å and the superficial area from 41 to ~230m2/g. The calcination process at different temperatures showed that the pillared material was stable until 600oC but the adequate temperature for calcination was 450oC. Materials prepared with different Al/Mont ratios showed the maximum Al incorporation for ratios >10meq Al/g and a good distribution for rations >15meq Al/g. |
