摘要
采用中心复合设计(CCD)对棕榈仁叶提取物(PKLE)作为绿色抑制剂的效果进行了研究。对提取物进行植物化学分析。本研究优化的工艺变量为:提取液浓度(0.5-1.5 g / l)、时间(3-5天)、温度(30-50℃)。用扫描电镜(SEM)进行了表面表征。从植物化学分析结果中观察到生物活性成分。最佳工艺水平为:抑制剂浓度(1.500 g/l)、温度(30℃)和时间(3 d)，抑菌率为96.74%;而经验证的最佳工艺水平为97.20%。扫描电镜结果表明，在验证的最佳工艺水平上观察到更多的薄膜。枸杞提取物是一种有效的抑制剂。
Optimization and corrosion inhibition of Palm kernel leaves on mild steel in oil and gas applications
This study investigated the effectiveness of palm kernel leaves extract (PKLE) as green inhibitor using Central Composite Design (CCD). Phytochemical analysis was performed on the extract. Process variables used for the optimization in this study were: concentration of extract (0.5–1.5 g per litre), time (3–5 days), and temperature (30–50 °C) respectively. Surface characterization was done with Scanning Electron Microscope (SEM). Bioactive constituents were observed from the result of the phytochemical analysis. The best process levels were: inhibitor concentration (1.500 g/l), temperature (30 °C) and time (3 days) with inhibition efficiency of 96.74 %; while the optimal process level validated gave 97.20 %. The SEM results revealed that more film was observed on the validated optimal process level. The PKLE extract was an effective inhibitor.
期刊介绍：
Egyptian Journal of Petroleum is addressed to the fields of crude oil, natural gas, energy and related subjects. Its objective is to serve as a forum for research and development covering the following areas: • Sedimentation and petroleum exploration. • Production. • Analysis and testing. • Chemistry and technology of petroleum and natural gas. • Refining and processing. • Catalysis. • Applications and petrochemicals. It also publishes original research papers and reviews in areas relating to synthetic fuels and lubricants - pollution - corrosion - alternate sources of energy - gasification, liquefaction and geology of coal - tar sands and oil shale - biomass as a source of renewable energy. To meet with these requirements the Egyptian Journal of Petroleum welcomes manuscripts and review papers reporting on the state-of-the-art in the aforementioned topics. The Egyptian Journal of Petroleum is also willing to publish the proceedings of petroleum and energy related conferences in a single volume form.
