中文摘要	针对油页岩灰渣利用率极低、大多以堆存处置的特点,在对油页岩进行热活化处理的基础上,借助XRD、SEM、IR、NMR、ICP等一系列微观测试分析工具对碱溶出前后油页岩的物质组成、结构特性以及硅、铝离子的溶出特性进行了研究。结果表明油页岩在20℃、1 mol/L NaOH溶液中经过7天溶解时,Si~(4+)和Al~(3+)的溶出量均随油页岩煅烧温度的变化而变化。其中900℃煅烧油页岩试样中的硅铝溶出量达到最大,该温度下油页岩胶砂试块强度也达到最大。油页岩在碱溶液中的离子溶出行为及其结构变化的研究为油页岩的化学反应活性评价及综合利用提供了理论基础。; Oil shale were calcined at different temperatures and their Si and Al ions dissolving-out characteristics in NaOH solution were examined by identical coupled plasma optical emission spectroscopy,and the mineral substance and structural characteristic of the silicon ion and aluminous character,and so on,have also been studied by means of XRD,SEM,IR,NMR etc.The result indicate that the dissolution amounts of Si~(4+)and Al~(3+)were changing with the calcined temperatures corroding in the Imol/l NaOH solution at 20℃,the dissolution amounts were maximized at 900℃and the compressive strength of oil shale based cememtitious material sand grout has also been maximized.Ion dissolution behavior and structure variation of the oil shale in the alkali solution has provided an experimental foundation and theory basic for the activity appraisal and massive utilization of oil shale.; 国家自然基金(50674062，50474002); 教育部973预研(104231)
