Characterization and Deposit Forming-Tendency of Polar Compounds in Cracked Components of Gasoline. Part 1. General Separation Scheme and Identification of Basic Fraction

Abstract:

Polar compounds were isolated tram are gollon of FCC by acid-base extraction followed by aluminum oxide adsorption chromatography. Fractions were tested with an Induction System Deposit (ISD) apparatus and the basic fraction was characterized by hydragen-1, carban-13 and nitrogen-15 NMR spectroscopy and GC/MS. The fraction resulting from the acid-base extraction and direct elution tram the chromatographic column showed a low sulfur content (114 ppm) and no detectable nitrogen. Fractions obtained by elutian from the chromatographic column with ethyl acetate and methanol showed a high tendency to form aeposits as tested by the ISD apparatus. The main compounds in the basic fraction were identified as methyl and dimethylanilines that showed low tendencies to deposit formation in ISD. © 1993, Taylor & Francis Group, LLC.
