Clay Activation With Sulfuric Acid Extruder. Actal Acid Clay Catalyst, Acid Activated Clay Manufacturers. During acid activation the interlayer cations are exchanged per protons and other catalytically active cations. Metal ions like Al amp Fe are leached out from octahedral layer of clay. As a result, clay becomes acidic and porous.
