Separation of nitrogenous materials from bitumen and heavy oils / H. Sawatzky ... [et al.].: M38-13/77-10E-PDF
"Separation of nitrogenous compounds and associated polar materials from deasphaltened Athabasca bitumen has been studied by modified API-USBM procedures. A pumping system was used and small fractions were collected to follow the extent of the separations. It was found that only limited elution or extraction of the ion exchange resins was required compared with the exhaustive extractions of the unmodified method. Some applications of the method have been made. Cold Lake bitumen, Lloydminster and Medicine River oils were studied. A heavy oil product from a severely hydrocracked Athabasca bitumen was also investigated. The fractions separated from Athabasca bitumen and its hydrocracked products were examined by infrared spectrometry. The main points of interest were the practically complete decarboxylation of carboxylic acids and the apparent large increase in carbazoles and indoles during hydrocracking"--Abstract, p. i.
