"The effect of hydrocracking on the distribution of nitrogenous components in Athabasca bitumen was investigated by studying products obtained at different severities. The components were separated by chromatography on anion and cation exchange resins using a modified method developed in connection with API project 60. The various fractions of nitrogenous and associated polar compounds were examined using infrared spectrometry and titration of the bases. Infrared data showed that carbazoles, indoles and related compounds, particularly in the asphaltenes increased substantially with hydrocracking severity. Basicity of the hydrocracked products which, too, increases with severity, is also discussed"--Abstract, p. i. Includes abstract in French. Hydrocracking Bitumen Nitrogen compounds Sawatzky, H.
