摘要: Solid superacids of sulfated zirconia were prepared by the sulfation gels, which obtained from mother solutions with different pH values. The gel precipitated at = 8 gave zirconia, showed highest catalytic activity and selectivity for skeletal isomerization n-pentane. active superacid was high reproducibility upon heating solution, followed washing precipitate hot water; this preparation procedure provided oxide small particle size. could be estimated exothermal peak caused crystallization in DTA.
