摘要
研究了盐酸对超稳Y型分子筛进一步脱铝改性的作用,发现随着盐酸用量的变化,其硅铝比也相应改变,分批加入盐酸脱铝。
It has been studied the
action of hydrochloric acid on further dealumination of USY zeolile and finded out that SiO 2/Al 2O
3 alters appropriately with the change of hydrochloric acid ration.When hydrocholoric acid is
added to dealuminate group by group,SiO 2/Al 2O 3 of the product is the same.
