Demineralization of petroleum cokes and fly ash samples obtained from the upgrading of Athabasca oil sands bitumen
Today's commercially proved technology to recover oil from the Athabasca oil sands, as practiced by Suncor and Syncrude, involves two major operations, namely: separation of the bitumen from the sand and upgrading of the bitumen to refinery oil. Significant amounts of petroleum coke are produced during the bitumen upgrading process. Suncor burns the bulk of its petroleum coke in boilers to fulfill the energy requirements of the entire operation, still meeting government regulations restricting the amount of sulfur dioxide that can be released to the environment. In contrast, Syncrude is able to burn only 20% of its coke production because of high sulphur dioxide emissions from elsewhere in its operations. The boiler ash (Fly ash) which contains appreciable amounts of metals, such as vanadium, nickel, titianium, iron, aluminum and other elements, is collected in the boiler hoppers and cyclones of the petroleum coke fired steam generation plants. There has been relatively little effort made towards the understanding of the chemical or physical nature of these materials. Knowledge of the physico-chemical properties of these materials will be helpful in assessing their beneficiation and potential use as fuel or metallurigcal coke and the feasibility of extracting some metals, especially Ni and V. In this communication the authors report studies of acid demineralization as a means of reducing ash content of these materials for /sup 13/C NMR spectroscopic investigations.
