Abstract: Oil sands mining and refining is an important way to solve the current energy shortage. The mineral components and pyrolysis characteristics of oil sands，including raw and demineralized samples，were investigated using X-ray diffraction （XRD） and thermogravimetric analysis （TGA）. The results show that the predominant mineral composition of oil sands，includes calcite，quartz，pyrite and clay，and a majority of minerals of oil sands，can be removed by acid method；the pyrolysis process of oil sands can be divided into two stages：dewatering stage and thermal cracking stage. The kinetic parameters，activation energy and frequency factor，of the main pyrolysis stage of oil sands were determined using Coast-Redfern integral method，and the activation energy of the pickling samples in varying degrees becomes higher than its original samples. The results provide a theoretical reference for industrializing oil sands treatment.
