The electrical heating experiments on oil shale sample from Huadian of Jilin were carried out by the pyrolysis method at three different heating rate 2 �� /min��5 �� /min and 10 �� /min in the temperature range of 30 �� �� 750 �森 Heating rate 2 �� /min is considered low��while intermediate one covers the range 5 �� /min and high heating rate is 10 �� /min�� The controlling parameters studied were the final pyrolysis temperature and the influence of the heating rate as well as type�� The heating rate has an important effect on the pyrolysis of oil shale and the amount of residual carbon obtained therefore�� It is found that increasing the heating rate and pyrolysis temperature also increases the production of oil and the total weight loss�� Higher heating rates resulted in higher rates of accumulation�� The rate of oil and water collection passed through the maximum of different heating rates at different pyrolysis temperatures�� Heating rate affected density��oil conversion and oil yield��
