制备条件对SO_4^(2-)/Al_2O_3固体超强酸性质的影响

The effect of preparation conditions on performance of SO_4^(2-)/Al_2O_3 solid superacid

本文以γ-Al2O3为载体,H2SO4溶液为浸渍液制备了SO24-/Al2O3超强酸催化剂。用正交实验的方法对SO42-/Al2O3超强酸的制备条件进行了考察,找到了决定SO42-/Al2O3酸性质的主要因素。

SO4^2-/Al2O3 superacid catalyst was prepared using γ- Al2O3 as the carrier and H2SO4 aqueous solution as the impregnation liquid. The preparation conditions were studied by orthogonal experiments and the dominant influencing factors of the acid properties of SO4^2-/Al2O3 superacid catalyst were found out.
