A PROCESS FOR THE SELECTIVE AROMATIC EXTRACTION FROM HYDROCARBON FEED STOCKS USING MIXED SOLVENT SYSTEM

摘要

The present disclosure provides a solvent system for the separation of aromatic compounds from hydrocarbon feedstock; said system comprises: 60 to 90 wt. % of N-methyl-2 pyrrolidone (NMP), 10 to 40 wt. % of at least one co-solvent (CS), 0.1 to 1 wt. % of at least one ionic liquid (IL), and 1 to 5 wt. % of water. The present disclosure also provides a process for the selective separation of aromatic compounds from hydrocarbon feed stocks.
