您要查找的是不是：
- 強B酸strong Broensted acid
- 隨著(zhù)HF濃度的繼續增加,強B酸變化不明顯,強L酸量增加,這是因為強B酸主要來(lái)源于缺陷處硅羥基,強L酸是由AlF3或其它鋁物種的形成。With increasing HF concentration,decrease in strong Br?nsted acid sites was less than that in weak Br?nsted acid sites because the hydroxyl groups bonded to Si (3730 cm -1 and 3745 cm -1 ) were more stable and strong. Lewis acid sites increased owing to the formation of AlF 3 or other fluorinated compounds.
- 各改性HZSM-5分子篩催化劑芳構化性能變化與表面酸性有關(guān),總酸量下降,芳構化活性下降,強B酸中心減少,深度裂解反應減少;With the decrease of total acidity, the activity of aromatization decrease. With the decrease of strong Bronsted acid sites, cracking reactions decrease.
