Abstract: We synthesized the novel chabazite-clay composite for better oilsands bitumen u pgrading via assembling chabazite on the kaolin surface under alkaline condition s. The chabazite-kaolin composite has such a unique exterior surface, accessibl e to large hydrocarbon molecules, that it could moderate oilsands derived bitume n upgrading reaction with high performance of contaminant (sulfur, nitrogen, ni ckel, and vanadium) removal.
