摘要:
为了实现超低硫柴油产品的生产,以三嵌段共聚物P123和正丁醇为混合模板剂,采用水热晶化法制备了介微孔复合材料ZSM-5-KIT-6(ZK),并将其负载活性组分NiMo,制备出加氢脱硫催化剂,并用X射线衍射,透射电镜,傅立叶变换红外光谱及N2吸附-脱附等表征方法对制备的催化剂进行了柴油加氢脱硫活性评价。研究了晶化温度从100 ℃升高到180 ℃对复合材料结构及其催化剂活性的影响。结果表明,在研究的温度范围内(100 ℃~180 ℃),随着晶化温度的升高,ZK复合材料的孔径变大,比表面积及孔容降低,结构的有序性变差;在柴油的加氢脱硫反应中,随着晶化温度的升高,催化剂的活性逐渐降低,当晶化温度为100 ℃时,催化剂活性最佳,脱硫率达到96.4%。
Abstract:
To deeply hydrodesulfurizate diesel fuel, the present study synthesizes the micro-mesoporous composite material ZSM-5-KIT-6 (ZK) as the hydrodesulfurization (HDS) catalyst support by hydrothermal crystallization method using triblock copolymers P123 and n-butanol as mixed templates. Ni and Mo were supported on ZK as the active components. The effects of the crystallization temperature on catalyst structure were characterized by X-ray diffraction, transmission electron microscopy, Fourier transform infrared spectroscopy and N2 adsorption-desorption methods. Moreover, the HDS catalytic performances of the prepared catalysts were evaluated. The results showed that the pore sizes of ZK composites increased with increasing crystallization temperatures from 100 ℃ to 180 ℃, while the specific surface area and pore volume decreased, the ordering of structure also became worse. The catalytic activity gradually decreased when crystallization temperature increased. At 100 ℃, the desulfurization rate reached up to 96.4%, showing the best catalytic activity.
