磁性Fe3O4@SiO2@MoS2催化剂制备及其FTIR和XRD光谱分析

FTIR and XRD Spectroscopic Analysis for the Preparation of Magnetic FeO@SiO@MoS Catalyst

随着原油重质化、劣质化趋势的加剧,浆态床加氢工艺重要性凸显。从改进催化剂的制备方法入手开发出高活性且可重复使用的重油改质催化剂,对于解决日益严重的能源和环境问题具有重要意义。制备出一种磁性Fe3O4@SiO2@MoS2重油改质催化剂。利用傅里叶变换红外光谱(Fourier-transform infrared spectroscopy,FTIR)和X射线衍射光谱分析(X-ray powder diffraction(XRD)spectra)研究了催化剂的制备过程和结构,发现该催化剂有效担载活性组分并且能有效降低重油的粘度。

In recent years,much attention has been focused on the slurry bed hydrocracking technologies because of the heavier crude oils and more strict environmental regulations.How to synthesize highly active and reusable catalyst is an important issue for the resolution of the present urgent problems in energy and environmental fields.In this work,magnetically recyclable Fe3O4@SiO2@MoS2 catalyst was developed for the heavy oil upgrading.The preparation and structure of the catalyst were investigated by FT-IR and XRD spectroscopic analysis methods.The results indicated that active compoments had been effectively deposited on the catalyst and the catalyst prepared can significantly reduce the viscosity of heavy oil.
