Abstract

In this study, immobilized CuAlO2 onto the ZSM-12&35 composite was prepared and used as a photocatalyst to remove N-containing oil pollutants (Carbazole) through advanced oxidation. In this method, acetone is used as a reaction solvent that can be partially converted to fuel oxygenates compounds (Octane enhancers) through an aldol condensation reaction. Photocatalyst characterization was performed using X-Ray Diffraction (XRD), Fourier-Transform Infrared Spectroscopy (FTIR), Field Emission Scanning Electron Microscopy (FESEM), Energy-Dispersive X-ray Spectroscopy (EDS), Mapping, and BET/BJH (Brunauer-Emmett-Teller & Barrett-Joyner-Halenda) techniques. The effect of operating parameters (contaminant concentration, catalyst dosage, and pH of the solution) on the efficiency of carbazole removal (model oil) was investigated through the RSM methodology. The removal products are identified by Gas Chromatography (GC-MAS) technique. The results indicated complete elimination of carbazole under mild conditions as well as the in-situ formation of typical fuel oxygenates compounds through aldol condensation among solvent molecules. Accordingly, this new protocol can be utilized to refine fuel products accompanied by enhancing their octane numbers.

新型光催化剂CuAlO2/ZSM-12&35完全去除油馏分中氮化合物的响应面优化建模

在本研究中，制备了固定化CuAlO2到ZSM-12和35复合材料上，并将其用作光催化剂，通过高级氧化去除含氮石油污染物（咔唑）。在该方法中，使用丙酮作为反应溶剂，该反应溶剂可以通过羟醛缩合反应部分转化为燃料含氧化合物（辛烷增强子）。使用X射线衍射（XRD）、傅立叶变换红外光谱（FTIR）、场发射扫描电子显微镜（FESEM）、能量分散X射线光谱（EDS）、图谱和BET/BJH（Brunauer-Emmett-Teller&Barrett Joyner-Halenda）技术进行光催化剂表征。通过RSM方法研究了操作参数（污染物浓度、催化剂用量和溶液pH）对咔唑去除效率（模型油）的影响。通过气相色谱（GC-MAS）技术鉴定去除产物。结果表明，咔唑在温和条件下完全消除，并通过溶剂分子之间的羟醛缩合原位形成典型的燃料含氧化合物。因此，这一新协议可用于精炼燃料产品，同时提高其辛烷值。
