Separation of Nitrogenous-Type Compounds from Synthetic Crudes

Abstract

This study describes the use of model compounds combined with gas chromatography analysis as a simple method to characterize complex adsorption systems and to obtain information on the adsorption mechanism. The possibility of using adsorbents for the selective removal of nitrogenous compounds from petroleum fractions is demonstrated. The adsorbent chosen in this study is ilmenite treated with bromide. The extent of removal is high for basic nitrogenous compounds but low for acidic/neutral nitrogenous compounds.
