Abstract
Chemical factors influencing bitumen-mineral adhesion have been examined by heat-of-immersion calorimetry. Two chosen minerals (quartz and calcite) and bitumen derived from Venezuelan and Middle East crude oils were characterised and the energy released by the bitumen-mineral interaction measured. Heat-of-immersion data are correlated with the concentration of heteroatomic species present in the bitumen and the structure of the mineral surfaces. Bitumen-quartz bonding is promoted by the presence of basic species in the bitumen and bitumen-calcite adhesion is favoured by the presence of acidic groups. A mechanism is proposed to account for the observed bond energies.
Zusammenfassung
Mittels Eintauchkalorimetrie wurden chemische Faktoren bestimmt, die die AdhÄsion zwischen Bitumen und Mineralstoffen beeinflussen. Es werden zwei Mineralstoffe (Quarz und Kalzit) sowie Bitumen aus Rohölen aus Venezuela und dem Mittleren Osten beschrieben und die durch Wechselwirkung zwischen Bitumen und Mineralstoff freigesetzte Energie gemessen. ImmersionswÄrmedaten wurden mit der Konzentration von Heteroatomen im Bitumen sowie mit der OberflÄchenstruktur des Mineralstoffes korreliert. Die Bitumen-Quarz-Bindung wird durch Gegenwart von basischen Komponenten im Bitumen gefördert, die Bitumen-Kalzit-AdhÄsion wird durch die Gegenwart sauerer Gruppen gefördert. Es wird ein Mechanismus vorgeschlagen, um die beobachteten Energien erklÄren zu können.
