摘    要:钴基费-托合成催化剂以介质阻挡放电等离子体(DBD法)替代传统热焙烧过程来制备,从而可在低温分解前驱体以获得高分散催化剂.结果表明,DBD法分解前驱体效果与传统焙烧法相同,但更节能和快捷.尽管两种方法所得催化剂的比表面积相近,但DBD法制得催化剂的孔体积和孔径更大,Co分散度更高,且Co与载体间的相互作用更强,因而更难...

关 键 词:等离子体处理  钴基催化剂  介质阻挡放电  前驱体分解  费-托合成

Abstract:To obtain a highly dispersed Co-based catalyst,dielectric-barrier discharge (DBD) plasma instead of calcination was used to decompose the precursors at low temperature.It was found that DBD plasma can not only replace calcination to get catalyst precursor decomposed but also be quicker and more energy-saving.The catalyst samples treated by the two methods had similar surface area,while pore volume and pore size of the sample treated by DBD was larger than that by calcination.Temperature-programmed reduction...
Keywords:plasma treatment  Co-based catalyst  dielectric-barrier discharge  precursor decomposition  Fischer-Tropsch synthesis
