摘要
对新疆塔城油页岩样品进行了理化性质分析及综合评价,研究了该油页岩的含油率、灰分、挥发分、发热量、热强度、硬度等特性,得知该油页岩含油率平均值为7.32%,灰分平均值为65.94%,挥发分平均值为20.41%,发热量平均值为4.55MJ/kg,热强度和硬度均与抚顺油页岩相似。分析了油页岩的灰分组成,主要成分为SiO2、Al2O3、Fe2O3、CaO和MgO,其中SiO2的质量分数最高,Al2O3、Fe2O3次之。综合考虑评价结果,选择抚顺式炉干馏工艺综合加工该油页岩。
The basic physicochemical characteristics of the Tacheng oil shales in Xinj iang province were investigated by a variety of experimental methods and a comprehensive evaluation was carried out.The properties of the oil shales such as oil yield,ash content, volatile component, calorific value, thermal intensity, rigidity and so on were investigated.The experimental result shows that the average oil yield is 7.32%,the average ash content is 65.94%,the average volatile component is 20.41%,the average calorific value is 4.55 MJ/kg,the thermal intensity and rigidity are both similar to the Fushun oil shales.In addition,the compositions of oil shales＇ash were analyzed and demonstrated to be SiO2 ,Al2 O3 ,Fe2 O3 , CaO and MgO.Among them,SiO2 is main composition,followed by Al2 O3 and Fe2 O3 .The comprehensive evaluation result shows that the basic physicochemical characteristics of the Tacheng oil shales in Xinjiang are close to that of Fushun oil shales, and the Fushun furnace retorting technology can suit the process of the Tacheng oil shale in Xinjiang.
