您要查找的是不是:
- 强B酸strong Broensted acid
- 随着HF浓度的继续增加,强B酸变化不明显,强L酸量增加,这是因为强B酸主要来源于缺陷处硅羟基,强L酸是由AlF3或其它铝物种的形成。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分子筛催化剂芳构化性能变化与表面酸性有关,总酸量下降,芳构化活性下降,强B酸中心减少,深度裂解反应减少;With the decrease of total acidity, the activity of aromatization decrease. With the decrease of strong Bronsted acid sites, cracking reactions decrease.
