Application:

Bentonite as a porous material is easily and abundantly found in nature. The possibility of using it as an industrial adsorbent and catalyst always exists and this field is the subject of many researchers› discussion. Activated bentonite is used as an active absorbent soil or color removal soil in various industries due to its specific surface area and high surface acid strength. The presence of olefins in aromatic compounds (benzene, toluene, xylenes) even in very small amounts can make these valuable intermediates of organic and petrochemical synthesis lacking desirable characteristics; Because under the relatively harsh conditions required for aromatics to continue industrial reactions, olefins, which are more reactive than aromatics, contaminate catalysts or create unwanted byproducts. On the other hand, since the amount of aromatic compounds in crude oil is much less than the increasing industrial needs, these valuable compounds are synthesized by the catalytic conversion process. In such a process, some olefin is inevitably produced. Although most of it is separated by distillation and solvent extraction, small amounts of olefin remain, and the deolefinization process by means of solid beds of activated bentonite is the only economic method for its complete removal.
