干馏

The yield of the gas was110Nm3/t~400Nm3/t at the range of retorting temperature 450℃~650℃.

在干馏温度450℃～650℃范围制得煤气110Nm3/t～400Nm3/t，煤气热值为14.7MJ／Nm3～17.5MJ／Nm3，属中热值煤气。

The convection heats that is apart from to 13 meters between the well heats the oil shale retorting mine process, heat the temperature as 600°C. Adopting single crack heating to need 4 years can make the whole hot solution district attain 500°C above, the adoption double crack heating need a year and can make whole hot solution the district attain 600°Cs or so.

3在井间距为13米的对流加热油页岩干馏开采过程中，加热温度为600℃，采用单裂缝加热需要4年就可使整个热解区域达到500℃以上，采用双裂缝加热需要1年就可使整个热解区域达到600℃左右。

Exchange the heating well and the oil extraction well that the much more above-mentioned well electricity heat the oil shale retorting mine, continue to heat to mine. 5 after years, the temperature that is apart from to heat the or so place of 6 meters of well is also only is 500°C, but heat whole temperatures of the nearby rock strata of wells all very high, cause the calories follow the peripheral rock strata in great quantities lost.

2将上述多井电加热油页岩干馏开采的加热井与采油井交换位置，继续加热开采。5年后，距加热井6米左右的地方温度也仅为500℃，而待采油页岩层与邻近地层的接触面处整体温度很高，说明在整个开采过程中油页岩层向邻近地层散失了大量的热。

The oil yield of six types of Huadian oil shales were measured on a Fischer assay retort,and the factors which effected the results of Fischer assay of oil shale were investigated,such as heating rate,particle size,final retorting temperature and retorting persistent time.

结果表明，页岩油的产率随着挥发分含量的增大而增加，在一定范围内提高升温速率，页岩油产率增大，但升温速率过快，反而使页岩油产率降低；终温在500℃~510℃，持温时间20 min的条件下，产油率最高，继续增加干馏终温和持续时间对产油率影响不大；同时适宜的粒度可以适当提高页岩油的产率。
