翻譯一段話,異丁烯脫氫方面

| 論文的第三部分主要是以不同孔徑硅膠及氧化鋁為載體,以CrOx為金屬活性組分、K2O為助催化劑,在連續(xù)微反裝置上對該催化劑的反應(yīng)性能進行了考察。在相同的條件下,得出以中孔氧化鋁為載體最佳;T=600℃時,以中孔氧化鋁為載體,CrOx負(fù)載量為15%,助催化劑K2O為2%時最佳(以下稱該負(fù)載量的催化劑為CBDH-07),此時,異丁烷的轉(zhuǎn)化率為54.69%,異丁烯的選擇性為90.34(前兩個小時的平均值)。 |

Ref. only, do not copy and use directly, please further modify and improve it prior to use. In section three of the thesis, the catalytic properties of the catalysts, which are constituted of different pore size silica gel or alumina as support, CrOx as active metal component and K2O as cocatalyst, were explored on a continuous micro-reactor. Under the sample experimental conditions, it was found that the mesoporous alumina is the best support. And the optimized experimental conditions are: T=600℃,mesoporous alumina support, 15% CrOx loading,2% K2O cocatalyst loading (the catalyst with such loadings will be referred to CBDH-07 in the following sections), giving the isobutane and isobutene conversion efficiencies as 54.69% and 90.34% ( the average values of the initial two hour reaction), respectively. |
