[求助] 请帮忙翻译一段话,催化方面

We speculate that coke accumulation on the HY support was not effectively inhibited by Mg, since addition of the Mg did not impact the catalyst acidity. Furthermore, the lower coke content of the Mg-doped Mo2C/HY catalysts compared to the Mo2C/HY must be due to improved Mo2C dispersion (since the acidities were the same), and hence the improved hydrogenation of the Mg-doped catalysts reduced coke formation. In the case of the K-Mo2C/HY catalyst, however, both decreased acidity and increased Mo2C dispersion reduced coke formation compared to the Mo2C/HY catalyst.

我们推测Mg不能有效抑制HY载体中焦炭的积累,加入Mg后并不能影响催化剂的酸度。而且,相比于未掺杂的Mo2C/HY 催化剂而言,Mg掺杂 Mo2C/HY 催化剂的低焦炭含量可能是由于 Mo2C 的分散性得到了提高(酸度还一样), ...

我的管理评价怎么提交不了啊?
