Feasibility Analysis of Some Clays as Adsorbents for Styrene Purification

Characterization of five clays （kaolinite, Fuller earth＇s, bentonite, pansil and sepiolite） is presented herein emphasizing their properties as adsorbent in the purification of styrene monomer. Polymerization assays have been carried out in order to determine what clays are suitable for the styrene monomer purification by an adsorption process, without promoting styrene polymerization. Some adsorption experiments have been also carried out in order to determine adsorption capacities of the proposed clays.
