【摘要】：在原油采出的过程中会产生一些副产物,其中老化油的存在不仅严重影响环境同时增加了生产管理难度,后期在三次采油的过程中产生了组分更为复杂的老化油,所以更难回收利用,因此催化裂解老化油既解决了废物的处理问题,保护了环境;同时也可以为油田生产节约成本,积极响应了国家倡导的可持续发展战略。根据已有的研究,本文在老化油催化裂解条件下选出最优催化剂进行试验,通过分析在催化裂解过程中裂解气产率、液体油产率和残渣率的变化,来讨论催化剂的种类、用量、粒径、反应温度和时间可能影响该产物的因素。研究和分析其裂解产物的性能和组成,并将裂解产物(优化催化剂条件下)应用在拖拉机发动机上进行验证试验。试验结果表明,第二种分子筛催化剂Re2O3(混合稀土)5%;Fe2O3 5%;活性炭30%;MgO 10%;SiO2 45%;K2O 5%,用量0.4%、反应温度460℃、反应时间120 min和粒径为2 mm条件下,老化油裂解燃料油的液体油产率较高,而残渣产率和裂解气产率相对较低。将裂解产物与0#柴油通过使用气相色谱-质谱联用(GC-MS)仪等仪器测出老化油裂解产物性能优良,密度与粘度均高于0#柴油标准;热值达到40 kJ/g;并且具有一定的低温流动性,冷滤点、冷凝点分别为6℃和2℃。将裂解产物应用在拖拉机发动机进行动力性及经济性验证结果表明与0#柴油相比,裂解产物功率相对较低,油耗量较大,转矩偏低,但仍然具有一定动力性能。通过将老化油裂解产物与乙醇、柴油混合后得出的LHY混合燃料进行试验结果表明其LHY混合燃料低热值比0#柴油低,因此LHY燃料的动力性较0#柴油下降;但不同LHY燃料的当量燃油消耗率低于0#柴油,具有一定的经济性。
[Abstract]:In the process of crude oil recovery, some by-products are produced, among which the existence of aging oil not only seriously affects the environment but also increases the difficulty of production management. In the later stage of tertiary oil recovery, the aging oil with more complex components is produced. So it is more difficult to recycle, so catalytic cracking aging oil can not only solve the problem of waste disposal and protect the environment, but also save the cost for oil field production, and respond positively to the sustainable development strategy advocated by the state. According to the existing research, the optimal catalyst was selected under the condition of catalytic cracking of aging oil. The types and dosage of catalyst were discussed by analyzing the variation of cracking gas yield, liquid oil yield and residue rate during catalytic cracking. Particle size, reaction temperature and time may affect the factors of the product. The performance and composition of the pyrolysis product were studied and analyzed. The pyrolysis product (under the optimized catalyst condition) was applied to the test of the tractor engine. The experimental results show that the second zeolite catalyst Re2O3 (mixed rare earth 5: Fe2O3 5), activated carbon 30% MgO10 / SiO2 45K2O5, the amount of 0.40%, the reaction temperature 460 鈩，
