Patent
·
OSTI ID:6418990
A process is described for purifying a hydrocarbon feedstock which contains at least one contaminant comprising aromatic compounds, said process comprising the consecutive steps of: (a) contacting a liquid feed stream of said hydrocarbon feedstock with an adsorbent comprising a zeolite under conditions suitable for the adsorption of said aromatic compounds by said zeolite to produce an aromatic compound-loaded zeolite; and (b) desorbing said aromatic compound-loaded zeolite using a desorbent comprising at least about 95% toluene.
