Production of clean fuel has recently become one of the most important goals for petroleum refining industries. The objective of this work is to obtain such clean fuel using simple and easy process under safe conditions. For this purpose, batch oxidative desulfurization (ODS) process is considered here to remove sulfur compounds found in light gas oil using a new composite synthetic homemade nano-catalyst. First the support for the new catalyst, which is HY zeolite nanoparticles, is prepared using sol-gel method. The support is then employed to generate the synthetic composite nano-catalyst which is made of copper oxide and nickel oxide using the impregnation method with different proportions of the active components such as: 5% CuO +25 % NiO, 10 % CuO +20 % NiO, 15 % CuO +15 % NiO, 20 % CuO +10 % NiO and 25 % CuO +5% NiO. An excellent distribution of the active metals with high surface area and pore volume as a result high activity has obtained. A fully automated batch reactor is used for the oxidative desulphurization of sulfur compounds and the performance of the new nano-catalyst at different safe reaction conditions (reaction temperature from 353−413 K, reaction time from 30−90 min) is evaluated in terms of sulfur removal.

通过分批氧化脱硫获得环保燃料的新型合成复合纳米催化剂

清洁燃料的生产最近已成为石油精炼行业最重要的目标之一。这项工作的目的是在安全条件下使用简单易行的方法获得此类清洁燃料。为此,这里考虑使用新型复合合成自制纳米催化剂,采用间歇氧化脱硫(ODS)工艺去除轻柴油中发现的硫化合物。首先,使用溶胶-凝胶法制备新型催化剂(HY沸石纳米颗粒)的载体。然后使用载体通过浸渍法生成由氧化铜和氧化镍制成的合成复合纳米催化剂,其中活性成分的比例不同,例如:5%CuO + 25%NiO,10%CuO + 20% NiO,15%CuO + 15%NiO,20%CuO + 10%NiO和25%CuO + 5%NiO。结果获得了具有高表面积和孔体积的活性金属的优异分布,因此具有高活性。全自动间歇式反应器用于硫化合物的氧化脱硫,并根据以下条件评估了新纳米催化剂在不同安全反应条件下的反应性能(反应温度为353-413 K,反应时间为30-90分钟)。脱硫。
