Study of the Olefin Removing Process from Aromatic Hydrocarbons by Activated Bentonite Beds

In this investigation the clay treating process which have used in petrochemical industries for olefine removing from aromatic products (benzene, toluene and xylenes) have been studied. The presence of olefines in aromatic products are objectionable because of their higher reactivity than aromatics. Olefins produce undesirable by-products in severe conditions which are required for downstream processing. The process was carried out through the fixed bed microreaclor which can simulate industrial conditions (200 psi and liquid phase). The selected range of temperature was 75-225 °C and the olefines were linear and cyclic. The obtained results from GC and GC/MS analysis of products showed that optimized temperature was 150-175°C and in these conditions the process carried out by alkylation reactions.
