页岩灰对油页岩低温干馏产物的影响

Impact of the Shale Ash on the Low-temperature Carbonization of the Oil Shale

分别介绍了油页岩低温干馏试验、油页岩与页岩灰掺混的干馏试验,结果表明,其他条件相同时,页岩灰与油页岩以4:1比例掺混时,油页岩干馏所产页岩油(凝点10℃,密度0.898 2g/cm3)与油页岩不掺混页岩灰干馏所得页岩油(凝点26℃,密度0.909 6g/cm3)相比,页岩油品质有所提升,有助于后续加工。

In the low-temperature carbonization process of the oil shale, the process conditions of the shale oil production in the presence of gray shale was introduced in this paper. The studies have shown that in the temperature around 520℃, comparing with shale oil （solidifying point of 26℃, density of 0.909 6g/em3） produced by distillation of oil shale without mixing gray shale, shale oil （solidifying point of 10℃, density of 0.898 2g/cm3） produced by distillation of oil shale under the dry distillation conditions of oil shale and gray shale in a ratio of 4：1, enjoys higher quality and is helpful for subsequent processing.
