【摘要】：在原油采出的過(guò)程中會(huì)產(chǎn)生一些副產(chǎn)物,其中老化油的存在不僅嚴(yán)重影響環(huán)境同時(shí)增加了生產(chǎn)管理難度,后期在三次采油的過(guò)程中產(chǎn)生了組分更為復(fù)雜的老化油,所以更難回收利用,因此催化裂解老化油既解決了廢物的處理問(wèn)題,保護(hù)了環(huán)境;同時(shí)也可以為油田生產(chǎn)節(jié)約成本,積極響應(yīng)了國(guó)家倡導(dǎo)的可持續(xù)發(fā)展戰(zhàn)略。根據(jù)已有的研究,本文在老化油催化裂解條件下選出最優(yōu)催化劑進(jìn)行試驗(yàn),通過(guò)分析在催化裂解過(guò)程中裂解氣產(chǎn)率、液體油產(chǎn)率和殘?jiān)实淖兓?來(lái)討論催化劑的種類、用量、粒徑、反應(yīng)溫度和時(shí)間可能影響該產(chǎn)物的因素。研究和分析其裂解產(chǎn)物的性能和組成,并將裂解產(chǎn)物(優(yōu)化催化劑條件下)應(yīng)用在拖拉機(jī)發(fā)動(dòng)機(jī)上進(jìn)行驗(yàn)證試驗(yàn)。試驗(yàn)結(jié)果表明,第二種分子篩催化劑Re2O3(混合稀土)5%;Fe2O3 5%;活性炭30%;MgO 10%;SiO2 45%;K2O 5%,用量0.4%、反應(yīng)溫度460℃、反應(yīng)時(shí)間120 min和粒徑為2 mm條件下,老化油裂解燃料油的液體油產(chǎn)率較高,而殘?jiān)a(chǎn)率和裂解氣產(chǎn)率相對(duì)較低。將裂解產(chǎn)物與0#柴油通過(guò)使用氣相色譜-質(zhì)譜聯(lián)用(GC-MS)儀等儀器測(cè)出老化油裂解產(chǎn)物性能優(yōu)良,密度與粘度均高于0#柴油標(biāo)準(zhǔn);熱值達(dá)到40 kJ/g;并且具有一定的低溫流動(dòng)性,冷濾點(diǎn)、冷凝點(diǎn)分別為6℃和2℃。將裂解產(chǎn)物應(yīng)用在拖拉機(jī)發(fā)動(dòng)機(jī)進(jìn)行動(dòng)力性及經(jīng)濟(jì)性驗(yàn)證結(jié)果表明與0#柴油相比,裂解產(chǎn)物功率相對(duì)較低,油耗量較大,轉(zhuǎn)矩偏低,但仍然具有一定動(dòng)力性能。通過(guò)將老化油裂解產(chǎn)物與乙醇、柴油混合后得出的LHY混合燃料進(jìn)行試驗(yàn)結(jié)果表明其LHY混合燃料低熱值比0#柴油低,因此LHY燃料的動(dòng)力性較0#柴油下降;但不同LHY燃料的當(dāng)量燃油消耗率低于0#柴油,具有一定的經(jīng)濟(jì)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，
