Activated clay is made of bentonite through acid activation, after acidification treatment, cations such as K+, Na+, Ca2+, Mg2+ and other cations between bentonite layers are converted into soluble salts of acid and dissolved, which weakens the binding force between the original layers, makes the lattice crack between layers, expands the layer spacing, increases the specific surface area and pore size, and significantly improves the adsorption capacity, so as to have stronger adsorption and catalytic activity; It can effectively catalyze esterification reactions, alkylation reactions, acylation reactions, cracking reactions, nucleophilic substitution reactions, etc.
Column support montmorillonite is a mineral material with two-dimensional pores formed by polymerizing inorganic cations or organic ions (molecules) inserted between montmorillonite layers, which has the characteristics of large specific surface area, good thermal stability, strong surface acidity and variable pore size, so it has broad application prospects in petrochemical, sewage treatment, antibacterial materials and other fields. The chemical activity of column support montmorillonite is particularly important when used in catalysts or catalyst carriers, because if the structure of the catalyst collapses at high temperatures, the catalytic activity is greatly reduced, so maintaining a stable structure is one of the necessary requirements for column support montmorillonite as a catalyst. It can be effectively used for F-T synthesis, catalytic cracking, disproportionation, alkylation and dehydration reactions.
