Abstract

1,156,838. Separating hydrocarbons. TEXACO DEVELOPMENT CORP. 4 Oct., 1966, No. 44363/66. Heading C5E. A method of treating a hydrocarbon oil comprising dicyclic aromatic hydrocarbons, monocyclic aromatic hydrocarbons, and non-aromatic hydrocarbons effecting separation of a first product fraction rich in said dicyclic aromatic hydrocarbons, a second product fraction rich in said monocyclic hydrocarbons and a third product fraction rich in said non-aromatic hydrocarbons comprises contacting said hydrocarbon oil with a solvent comprising furfural at selective conditions in a first contacting zone, effecting separation of a first extract-mix comprising said first product fraction and a first raffinate comprising monocyclic hydrocarbons and non-aromatic hydrocarbons, separating said first product fraction from said first extract mix, contacting said first raffinate with a solvent comprising furfural at conditions effecting extraction of aromatic hydrocarbons to the substantial exclusion of non-aromatic hydrocarbons in a second contacting zone, effecting separation of a second extract-mix comprising said second product fraction and a second raffinate comprising said third product fraction, separating said second product fraction from said second extract-mix, and separating said third product fraction from said second raffinate. The charge oil may be a catalytically cracked gas oil containing 20 to 30% dicyclic aromatics, 20 to 30% monocyclic aromatics and 40 to 60% non- aromatic hydrocarbons and boiling within the range of 400 to 600‹ F. A light paraffin backwash may be used to increase the selectivity. The extract-mix from the second extraction step may be cooled to separate a fraction of intermediate aromaticity which is recycled to the primary extraction process.
