Abstract

The present study focuses on using the adsorption character of the layered double hydroxide (LDH) for removal of aromatics species because of its simple production, suitable for ecology, cost less and easy to modify by intercalation organic molecules which cause change from hydrophilic to hydrophobic character and help in increase the removal percentage of mono- and di- aromatics. In this work, nanolayered structures (AlZn NLS) were prepared and characterized by different techniques but cannot remove aromatics. After intercalation by organic molecules (4-aminobenzoic acid, Salicylic acid, Adipic acid and n-capric acid in order), series of AlZn nanohybrids were prepared and showed significant removal of mono- and di-aromatics. The prepared nanohybrids based on n-capric acid showed significant results for removal of both mono-aromatics (33.5%) and di-aromatics (28.6%). The current study concluded that the nanolayered structures of AlZn became effective for removal aromatic species because of the expansion of the interlayered spacing of nanolayers and the increase of hydrophobic character.

设计双功能纳米杂化物，通过去除苯基壬烷和甲基萘来改善石油馏分

层状双氢氧化物(LDH)具有制备简单、生态适宜、成本低、易于嵌入有机分子修饰等特点，可使其由亲水性转变为疏水性，有利于提高单体和二芳烃的去除率，是本研究的重点。在本工作中，制备了纳米层状结构(AlZn NLS)，并通过不同的技术对其进行了表征，但不能去除芳烃。用有机分子(4-氨基苯甲酸、水杨酸、己二酸和正癸酸)插层后，制备了一系列AlZn纳米杂化物，并对单芳烃和二芳烃有明显的去除效果。制备的n-癸酸纳米杂化物对单芳烃(33.5%)和双芳烃(28.6%)的去除率均显著。本研究认为，AlZn的纳米层状结构由于其层间间距的扩大和疏水性的增强而成为去除芳香族物质的有效材料。

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.
