A strategy for clean fuel by selective adsorption processing was deemed to be convenient and environmental-friendly in past decades. However, the development of adsorption desulfurization was tremendously subject to the fabrication of high-performance adsorbents with large capacity and high stability. Herein, we designed a novel route to fabricate the cloth-like carbon nanofiber film with a hierarchical porous structure by electrospinning. The structure and properties of the cloth-like carbon nanofiber films were determined by a series of characterizations. Subsequently, the desulfurization performance of the cloth-like carbon nanofiber films was examined by the simulated thiophene (TH) oil. Furthermore, the effect of adsorption conditions on the adsorption capacity was intensively investigated, such as carbonization temperature, initial concentration and desulfurization temperature. The results found that at optimal calcination temperature of 700 °C, the cloth-like carbon nanofiber films possessed the highest micropore volume (V_mic = 0.185 m³/g) and adsorption capacity (q_e = 96.6 mg/g) at 800 mg/L initial concentration under the adsorption temperature of 25 °C. The results corroborated that the physical properties of the cloth-like carbon nanofiber films with the surface area of 417.8 m²/g, the total pore volume of 0.187 cm³/g and average pore diameter of 1.36 nm had an important influence on the high adsorption capacity. On this basis, the adsorption experimental data were best fitted to pseudo-second-order kinetic and Langmuir isotherm models. Furthermore, the other highlight of the cloth-like carbon nanofiber films was convenient for the separation from oil, thus achieving the desirable reused performance.

在过去的几十年中，通过选择性吸附处理的清洁燃料策略被认为是方便且环保的。然而，吸附脱硫的发展极大地受制于具有大容量和高稳定性的高性能吸附剂的制造。在这里，我们设计了一种新颖的方法，通过静电纺丝来制造具有分层多孔结构的布状碳纳米纤维薄膜。布状碳纳米纤维薄膜的结构和性能是通过一系列表征确定的。随后，通过模拟噻吩（TH）油检查了布状碳纳米纤维薄膜的脱硫性能。此外，深入研究了吸附条件对吸附容量的影响，例如碳化温度，初始浓度和脱硫温度。结果发现，在最佳煅烧温度为700°C时，布状碳纳米纤维薄膜具有最大的微孔体积（V_mic  = 0.185 m ³ / g）和 在25°C的吸附温度下初始浓度为800 mg / L时的吸附容量（q _e = 96.6 mg / g）。结果证实了表面积为417.8 m ² / g，总孔体积为0.187 cm ³ / g，平均孔径为1.36 nm的布状碳纳米纤维薄膜的物理性能对高碳纤维的生产具有重要影响。吸附能力。在此基础上，吸附实验数据最适合拟二阶动力学模型和Langmuir等温模型。此外，布状碳纳米纤维膜的另一个亮点是便于从油中分离，从而实现了理想的重复使用性能。
