Abstract

Recovery of pure aromatics from reformate gasoline comprises: (a) selectively hydrogenating the reformate gasoline, where the conditions are adjusted so that the non-aromatics, esp. olefins, diolefins and triolefins, are hydrogenated; and (b) removing the selectively hydrogenated and aromatics-containing products by extractive distillation and/or by liquid-liquid extraction to aromatics and non-aromatics. An apparatus for carrying out the process is also claimed.
