摘　　要：对窑街油页岩和龙口油页岩采用酸洗处理,脱除矿物质后采用美国康塔公司生产的AWTOSOB自动吸附仪,对脱矿物质前后的两种油页岩以及所制得的半焦进行低温氮吸附实验。结果表明:脱矿物前后的油页岩及半焦均拥有从小至分子级到大至无上限的较连续的完整的孔系统,且脱矿物质改变油页岩的孔结构,使其比表面积和孔径增大,通过傅里叶红外(FT-IR)表征脱矿物质前后的油页岩,得到矿物质特征峰的消失以及有机官能团的增多导致了油页岩孔结构发生变化。The minerals of oil shales from Yaojie and Longkou are removed by acid treatment. Then, using AWTOSOB automatic adsorption instrument produced by American Contador Company, low temperature nitrogen adsorption experiment is carried out with the raw and treated oil shales and semi - coke oil shales. The analysis results show that the raw and treated oil shales and its semi - coke oil shales integrated pore system range from molecular scale to structure is changed and the surface area and minerals. The characteristic peak of minerals lead to change the pore structure of oil shales continuous and upper limit scale in this samples. The pore total volume of the pore increased of oil shales by detaching disappearing and the organic functional groups increasing through FT - IR of the raw and treated oil shales.
