REMOVAL OF LIGHT ALKYLATED AROMATICS FROM THE HEAVY ALKYLATED AROMATICS STREAM

摘要

A process for increasing the production of monoalkylbenzenes is presented. The process includes utilizing a transalkylation process to convert dialkylbenzenes to monoalkylbenzenes. The feed to the transalkylation process has alkylated toluenes and alkylated ethylbenzenes and other alkylated aromatics having small alkyl groups with less than 8 carbons removed to improve the efficiency of the transalkylation process. The recycled dialkylbenzenes and a portion of the recycled benzene are converted to monoalkylbenzenes.
