Description

一种油页岩渣及干馏钻井油屑渣无害化利用的方法A method for harmless utilization of oil shale residue and retort drilling oil cuttings residue 技术领域Technical field
本发明属于油页岩渣及干馏钻井油屑渣利用领域，具体涉及一种油页岩渣及干馏钻井油屑渣无害化利用的方法。The invention belongs to the field of utilization of oil shale residue and retort drilling oil cuttings residue, and specifically relates to a method for harmless utilization of oil shale residue and retort drilling oil cuttings residue.
背景技术Background technique
油页岩作为一种由细粒矿物碎屑和低等动植物残体腐解的有机质同时沉积形成的高灰分可燃烧有机岩石，主要用作干馏提炼页岩油或者直接燃烧发电。油页岩经300-700℃热解后的半焦在工业锅炉燃烧或油页岩直接在工业锅炉燃烧后产生的油页岩渣，占到油页岩总量的60％以上。目前，绝大多数的油页岩渣依旧处于露天堆积状态，油页岩渣堆积占据了大量的土地资源,易导致滚石、滑坡、泥石流等地质灾害，经降雨、淋漓等作用，对土壤和环境造成严重危害，并且油页岩渣会污染地下水资源以及污染空气，所以长期堆放会对环境造成破坏以及对人类健康造成难以估量的影响。油页岩渣及干馏钻井油屑渣所含的主要矿物有石英、高岭石、赤铁矿、云母、刚玉、白云石、硫铁矿等，属于含有少量残炭的类似火山灰质原料，有一定的颗粒度。由于在干馏或燃烧过程中，去除了其中的挥发分、碳质或其它有机酸等，形成多孔结构，具有很好的活性。油页岩渣的主要成分为SiO2、Al2O3、Fe2O3、MgO、CaO、SO3等。因此在油页岩开发利用过程中，不仅要提高油页岩中有机质的利用效率，更要拓宽油页岩渣的利用途径。 Oil shale is a high-ash combustible organic rock formed by the simultaneous deposition of fine-grained mineral debris and decomposed organic matter from lower animal and plant residues. It is mainly used for retorting to refine shale oil or directly burning it to generate electricity. The oil shale residue produced when the semi-coke of oil shale is pyrolyzed at 300-700°C is burned in an industrial boiler or the oil shale is directly burned in an industrial boiler, accounting for more than 60% of the total oil shale. At present, the vast majority of oil shale residue is still accumulated in the open air. The accumulation of oil shale residue occupies a large amount of land resources, which can easily lead to geological disasters such as rolling rocks, landslides, and debris flows. Through rainfall, dripping, etc., it has a negative impact on the soil and environment. Cause serious harm, and oil shale residue will pollute groundwater resources and pollute the air, so long-term accumulation will cause damage to the environment and have an immeasurable impact on human health. The main minerals contained in oil shale residue and retort drilling oil residue include quartz, kaolinite, hematite, mica, corundum, dolomite, pyrite, etc. They are volcanic ash-like raw materials containing a small amount of residual carbon. A certain degree of granularity. Due to the removal of volatile matter, carbonaceous or other organic acids during the dry distillation or combustion process, a porous structure is formed and has good activity. The main components of oil shale residue are SiO2, Al2O3, Fe2O3, MgO, CaO, SO3, etc. Therefore, in the process of oil shale development and utilization, it is not only necessary to improve the utilization efficiency of organic matter in oil shale, but also to broaden the utilization methods of oil shale residue.
目前，油页岩的主要利用方式有：1)制备精细化工材料，如提取白炭黑、提取氧化物、用作塑料和橡胶的填充剂；2)制备建筑材料，如水泥、陶粒、轻质砖、玻璃、沸石等；针对利用方式2)。公开号为CN108516734A的中国专利公开了“一种油页岩废渣制备长寿命环保排水型沥青路面的方法”，该方法是将油页岩渣颗粒料作为细集料的替代物添加到粗集料中，并和矿粉以及沥青进行混合，从而形成一种沥青路面，其中的沥青采用的是由基质沥青和硅烷偶联剂混合形成的改性沥青，在该方法中，通过石料、油页岩废渣、基质沥青和硅烷偶联剂的相互配合，且其中的油页岩渣颗粒是起到替代细集料的作用且得到的是沥青路面，属于终端产品，利用范围较窄，且油页岩废渣颗粒的低强度和低耐磨性导致沥青路面耐久性显著下降，显然不符合沥青路面用集料技术指标。此外，也有用于农业肥料和土壤的改良剂，但对土壤或地下水有一定污染性；上述诸多利用方式的利用量有限且附加值低，为实现油页岩渣及干馏钻井油屑渣的可持续利用需寻求一条附加值高、应用范围广的油页岩渣利用途径迫在眉睫。At present, the main utilization methods of oil shale are: 1) Preparation of fine chemical materials, such as extracting silica, extracting oxides, and using them as fillers for plastics and rubber; 2) Preparing construction materials, such as cement, ceramsite, light Quality bricks, glass, zeolite, etc.; for use method 2). The Chinese patent with publication number CN108516734A discloses "a method for preparing long-life environmentally friendly drainage asphalt pavement from oil shale waste residue". This method is to add oil shale residue particles to coarse aggregate as a substitute for fine aggregate. in, and mixed with mineral powder and asphalt to form an asphalt pavement. The asphalt uses modified asphalt mixed with base asphalt and silane coupling agent. In this method, stone and oil shale are used. The interaction of waste residue, matrix asphalt and silane coupling agent, and the oil shale residue particles in it are used to replace fine aggregate and the resulting asphalt pavement is an end product with a narrow utilization range, and oil shale The low strength and low wear resistance of waste residue particles lead to a significant decrease in the durability of asphalt pavement, which obviously does not meet the technical indicators of aggregates for asphalt pavement. In addition, there are also agricultural fertilizers and soil improvers, but they have certain pollution effects on soil or groundwater. Many of the above utilization methods have limited utilization and low added value. In order to realize the reproducibility of oil shale residue and retort drilling oil cuttings residue, For sustainable utilization, it is urgent to find a way to utilize oil shale residue with high added value and wide application range.
