摘要
本文对硫含量为 1158×10-6 的原油进行了深入研究,使用两种合成的纳米催化剂(CuO/SiO2,CuO/TiO2-SiO2)进行氧化脱硫.通过X射线分析、傅里叶变换红外光谱、热重分析等方法检测载体和催化剂的性能.实验结果表明,催化剂具有强烈的金属-载体相互作用、良好的活性金属分散性和较大的比表面积.采用自动间歇式反应器进行脱硫实验,并在不同的中等反应条件下(反应温度353～413K,反应时间 40～100min)测试催化剂的脱硫效果.结果发现,合成的纳米催化剂的表面积和孔体积活性金属分散方式适当,在 413 K和100min下,CAT-1 和CAT-2 的脱硫效率分别达到了87%和99.2%,为低硫含量的原油生产提供了新思路.
Abstract
In this study,crude oil with a sulfur content of 1158×10-6 was intensively investigated for oxidative desulfurization using two synthetic nanocatalysts(CuO/SiO2,CuO/TiO2-SiO2).The performance of the carriers and catalysts was examined by X-ray analysis,Fourier transform infrared spectroscopy,and thermogravimetric analysis.The experimental results showed that the catalysts had strong metal-carrier interactions,good active metal dispersion and a wide range of surface morphologies.The desulfurization experiments were carried out using an automated intermittent reactor and the desulfurization effect of the catalysts was measured under different moderate reaction conditions(reaction temperature of 353～413K and reaction time of 40～100min).It was found that the surface area and pore volume of the synthesized nanocatalysts were dispersed in an appropriate manner for the active metals,resulting in desulfurization efficiencies of 87%and 99.2%for CAT-1 and CAT-2 at 413K and 100min,respectively,which could provide new ideas for the production of crude oil with low sulphur content.
