摘要
以均匀沉淀法合成金属氧化物改性介孔二氧化硅,并通过气体穿透实验考察了其吸附H_2S气体的性能。实验表明,CuO负载量为40%(质量分数)、450℃下焙烧4h制备的改性二氧化硅具有最佳的吸附性能,其穿透时间为247.3min,穿透吸附量达50.5mg/g。
The paper shows that the metallic oxide modification and meso-porous silicon dioxide is composed by the homogeneous precipitation method, and its performance of sulfureted hydrogen gas absorption is studied by gas penetration experiment. The results showthat the best adsorption performance achieves at a 40% CuO load, and a baking temperature under 450℃ for 4 hours. The adsorption shows a penetration time of 247.3 minutes and a penetration adsorption capacity of 50.5mg/g.
