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

SO2-4/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 SO2-4/Al2O3 superacid catalyst were found out.
