摘　　要：对油页岩进行了扫描电镜分析,测定了油页岩的密度、可磨性、灰分特性、比热、含油率等物性参数,并采用热重分析仪详细研究了油页岩样品在典型工况下的热解及燃烧特性。结果表明,桦甸油页岩是一种高灰分、高挥发分、低热值和具有中等结渣倾向的劣质燃料;不同矿区的油页岩的品质有区别,其中大城子四层的油页岩品质较好,公郎头十一层较差。利用热解和燃烧的实验数据建立的油页岩热解及燃烧的动力学模型表明,油页岩的热解反应属于一级反应,其燃烧反应在不同的温度范围内可用不同的反应级数来描述。The basic physicochemical characteristics of the Huadian oil shales were investigated in detail by a variety of experimental methods. The surface structure of the oil shales was measured with SEM. The properties of the oil shales such as density, grindability, ash characteristics, specific heat capacity, oil yield and so on were also investigated. In addition, the pyrolysis and combustion charaeteris tics of the oil shales were also measured using the thermal gravitational analysis apparatus. The results show that the Huadian oil shale is a kind of low-grade fuel with high ash, high volatile and low calorific value. Oil shale quality differs in different mine areas. the Gonglangtou＇s. Based on experimental results, By comparison, the Dachengzi＇s were better than pyrolysis and combustion kinetic models related were proposed. The results show the oil shale pyrolysis reaction is to be described by the first order kinetics. And different reaction orders at different temperature is required to describe the combustion reaction of the oil shales.
