SIMPLE ROUTE FOR ACTIVATING NATURAL CLAYS STRUCTURED IN THE FORM OF INTEGRAL MONOLITHS, EXTRUDED IN THE FORM OF HONEYCOMB THROUGH MODIFICATION OF THE TEXTURAL PROPERTIES THEREOF

摘要

A simple method is proposed for activating monoliths of natural clays in the form of honeycomb, consisting in mixing the clay with charcoal prior to extrusion, subsequently burning the carbon of the monolith through calcination in air at moderate temperatures. There is an improvement in the natural properties of the clay and, as a consequence, in the adsorbent capacity thereof, without significantly modifying its initial structure, moreover slightly increasing the mechanical strength thereof with respect to the same clay monoliths not having been doped.
