Abstract: The pyrolysis of Zhalaiteqi oil sand was undertaken with a fixedbed reactor under nitrogen atmosphere. Effects of pyrolysis temperature, time and flow rate of carrier gas on the oil and water yield were analyzed in detail. Optimum pyrolysis condition of the oil sand was determined as well. The oil yield from NO.2 and NO.6 oil sand is 12.55% and 7.18%, respectively. It is 22.92% and 43.03%, respectively, higher than the carbonization result with aluminum retort. The results indicate that pyrolysis is a good way for Zhalaiteqi oil sand to produce oil.
