With the aim of providing clean fuels through the desulfurization, the nanocomposite of Nitrogen-doped carbon nanotube/ZiF-8 (NCNT/ZIF-8) was prepared via the hydrothermal method. The nanocomposite sorbents were evaluated in the adsorption of dibenzothiophene (DBT) from the liquid phase. In this regard, the microstructure, morphology, particle size, thermal stability and physicochemical properties of nanoadsorbents were determined by using different characterization techniques. Influences of various parameters on the adsorption capacity of the nanoadsorbents were investigated; such as the adsorbent type, adsorption time, temperature and the initial DBT concentration. The as-prepared nanoadsorbents, ZiF-8 and NCNT/ZIF-8, possessed a high surface area of 1123.9 and 1207.4 m²/g, respectively. The NCNT/ZIF-8 exhibited the DBT adsorption capacity of 81.2 mg/g which is much higher than that of the pure ZIF-8 (69.1 mg/g). This excellent performance can be ascribed to the synergistic effects of both NCNT and ZiF-8, the presence of basic groups in the NCNT structure, and the high surface area and pore volume. Moreover, the DBT equilibrium adsorption was investigated by using Langmuir, Freundlich models. The Langmuir isotherm indicated a good agreement with experimental results. In addition, adsorption kinetics were studied and it was revealed that the pseudo-second-order model exhibited a favorable fitting with the experimental data. Finally, the regenerated NCNT/ZIF-8 provided a good performance even after 3 adsorption-desorption cycles and its adsorption capacity was almost unchanged.

为了通过脱硫提供清洁燃料，通过水热法制备了掺氮碳纳米管/ ZiF-8（NCNT / ZIF-8）的纳米复合材料。在液相中对二苯并噻吩（DBT）的吸附中评估了纳米复合吸附剂。在这方面，通过使用不同的表征技术确定了纳米吸附剂的微观结构，形态，粒度，热稳定性和理化性质。研究了各种参数对纳米吸附剂吸附能力的影响。例如吸附剂类型，吸附时间，温度和DBT初始浓度。制备的纳米吸附剂ZiF-8和NCNT / ZIF-8具有1123.9和1207.4 m ²的高表面积/ g。NCNT / ZIF-8的DBT吸附容量为81.2 mg / g，远高于纯ZIF-8的DBT吸附容量（69.1 mg / g）。这种出色的性能可归因于NCNT和ZiF-8的协同作用，NCNT结构中存在碱性基团以及高表面积和孔体积。此外，使用Langmuir，Freundlich模型研究了DBT平衡吸附。Langmuir等温线表明与实验结果吻合良好。另外，对吸附动力学进行了研究，结果表明，拟二级模型与实验数据具有良好的拟合性。最后，再生的NCNT / ZIF-8即使经过3次吸附-脱附循环也提供了良好的性能，其吸附容量几乎不变。
