    Oil sands are sometimes referred to as tar sands or bituminous sands. The exact composition of Alberta's oil sands can vary greatly, even within the same geological formation. A typical oil sands deposit contains about 10% bitumen, 5% water and 85% solids. However, the bitumen content can be as high as 20% in some areas.

  • Effect of CaO additive on co-pyrolysis behavior of ...

    2020-04-01  The results show that both the heating rate and the addition of CaO have an important influence on the co-pyrolysis of coal and cow dung. As the heating rate increases from 5 to 25 °C/min, the negative synergistic effect for the yield of char weakens during the co-pyrolysis when no CaO is added to the MHJ and CD. CaO partly delays the pyrolysis of CD and declines the pyrolysis
