The changes in the chemical composition of Athabasca bitumen due to thermal hydrocracking under varying severities of treatment were studied. The main reaction appeared to be the cleavage of saturated hydrocarbon structures from aromatic clusters resulting in large increases in the saturated hydrocarbon structures from aromatic clusters resulting in large increases in the saturated hydrocarbon fraction as well as decreases in molecular weights. The mononuclear aromatic fraction increased very substantially in weight with severity of treatment but the increase in the number of mononuclear aromatic structures was even more marked. The dinuclear aromatic fraction decreased in weight but the number of these structures increased. The polynuclear aromatic and polar fractions decreased markedly in weight but the number of polynuclear aromatic structures changed slightly. The most severe treatment almost eliminated the asphaltenes and the basic materials. The changes in sulfur contents in the various fractions were followed and discussed. Attempts are being made to explain the low hydrogen consumption during these treatments by thermal hydrogen transfer-aromatization reactions.
