CONTINUOUS PROCESS FOR REMOVING IMPURITIES FROM IMPURE HEAVY ALKYLATED BENZENE (HAB) AND REGENERATING AN EXHAUSTED ADSORBENT

摘要

The present disclosure provides a process for the removal of impurities from impure heavy alkylated benzene (HAB) using an adsorbent. The adsorbent can then be regenerated by using a non-carcinogenic and eco-friendly fluid medium, which can be recovered and reused. The process of the present disclosure avoids the use of steam for regeneration/displacement of impurities from the adsorbent and hence, minimizes effluent generation having higher COD.
