Abstract: The potential oil yield of Karamay oil sand was measured on a Fischer assay retort, and the effect of factors, such as oil sand particle size, heating rate, final retorting temperature and retorting time, on the determination result was investigated. As a result, the optimum conditions of measuring the oil yield of oil sand were obtained as follows: the particle sizes of oil sands should be in the range of 3～5mm, using a heating rate of 15℃/min, the final retorting temperature was 500℃ and maintaining at 500℃ for 20 min. It was also found that satisfied result of water extraction was obtained by using xylene as solvent. Test results showed that the determination results of this method were in good agreement with the conventional Dean-Stark toluene extraction method.
