在这项工作中,本发明提供了一种有效解聚木质素和可控产物分布的有益方法。木质素,丰富的芳香生物聚合物,具有生产各种生物燃料和化学吸附剂的潜力,有望有利于未来的循环经济。微波-超声(MW/US)辅助的木质素的有效解聚提供了用于制造待研究的起始材料的一些芳族材料。一些基于Ni2+的纳米有机金属表面活性剂(NOMS),Cu2+,Co2+,Fe3+,除了2-羟基萘-磺胺之外,还合成了Mn2+以提高石油采收率(EOR)。在这项工作中,通过动态界面张力(IFT)的研究,对NOMS效率的评估是提高重油采收率,接触角,和化学洪水情景。NOMS-Ni2表现出最大的粘度和屈服值降低。研究了在40、60和80°C的温度下,将粘度分别从空白原油粘度9978.8、8005.6和5008.6Pas降至819.9、659.89和499.9Pas。τB值的降低也通过OMS-Ni2获得。针对Ni2衍生物(0.1×10-1mNm-1)记录了最小IFT。用NOMS-Ni2+表面活性剂实现了完全的润湿性改变(约6.01)。在50°C和499psi作为注入压力下,使用砂粒模型作为多孔介质,在表面活性剂浓度(1、1.5、2和2.5%)下进行了3组驱油测试。与相同浓度的其他NOMS-M2相比,NOMS-Ni2形成的最佳值(OR)分别为62、81、85.2和89%。文中描述了交替润湿性的机理。在40、60和80°C的温度下研究用过的重质原油的流变学。
In this work, a beneficial approach for efficient depolymerization of lignin and controllable product distribution is provided. Lignin, an abundant aromatic biopolymer, has the potential to produce various biofuels and chemical adsorption agents and is expected to benefit the future circular economy. Microwave-ultrasonic (MW/US) assisted efficient depolymerization of lignin affords some aromatic materials used in manufacturing the starting material to be investigated. Some nano organometallic surfactants (NOMS) based on Ni2+, Cu2+, Co2+, Fe3+, and Mn2+ besides 2-hydroxynaphth-sulphanilamide are synthesized to enhance oil recovery (EOR). In this work, the assessment of the NOMS\'s efficiency was improving the heavy oil recovery via the study of the dynamic interfacial tension (IFT), contact angle, and chemical flooding scenarios. The NOMS-Ni2+ exhibited the maximum reduction of viscosity and yield values. Dropping the viscosity to 819.9, 659.89, and 499.9 Pa s from blank crude oil viscosity of 9978.8, 8005.6, and 5008.6 Pa s respectively at temperatures of 40, 60, and 80 °C was investigated. The reduction of τB values was obtained also by OMS-Ni2+. The minimum IFT was recorded against the Ni2+ derivatives (0.1 × 10-1 mN m-1). The complete wettability alteration was achieved with the NOMS-Ni2+ surfactant (ɵ ≅ 6.01 ) . The flooding test has been steered in 3 sets using the sand-packed model as a porous media at surfactant concentrations (1, 1.5, 2 and 2.5%) at 50 °C and 499 psi as injection pressure. The best value (ORs) formed for NOMS-Ni2+ were 62, 81, 85.2, and 89% respectively as compared with other NOMS-M2+ at the same concentrations. The mechanism of alternating wettability was described in the text. The rheology of the used heavy crude oil was investigated under temperatures of 40, 60, and 80 °C.
