NITROGEN-COMPOUNDS IN PYROLYSIS PRODUCED LIQUIDS FROM 2 TURKISH OIL SHALES

Shale oils produced by pyrolysis of oil shales of the Goynuk and Seyit omer regions in Turkey were analyzed for basic nitrogen compounds. Bas ic nitrogen compounds were removed from the oil by HCI treated silica gel. Total shale oil, basic, acidic, and neutral fractions were compar ed. It was found that basic nitrogen accounted for about one half of a ll nitrogen in Goynuk shale oil, whereas 68% of the total nitrogen was basic in Seyitomer shale oil. The basic nitrogen compounds also inclu ded some acidic and neutral nitrogen. Nitriles were also present in sh ale oils but not detected if the oils were treated with NaOH prior to pyrolysis, suggesting that the formation of nitriles may be due to the reaction of fatty acids with ammonia released from the inorganic matr ix.
