硫酸氢钠是一种重要的无机盐化工原料及无机盐固体酸催化剂，但在实际使用中存在诸多缺陷．以廉价凹凸棒黏土（凹土）为载体开发高附加值的固体酸催化剂，研究了提高凹土比表面积与成型的方法；分别运用浸渍法和热分散法制备了复合固体酸催化剂，并考察了这两类催化剂对环己醇脱水反应的催化性能．结果表明，凹土比表面积可达233.7 m2／g，环己醇脱水时间由54 min缩短到30 min．

Sodium bisulfate is a kind of important inorganic raw materials in chemical engineering and inor-ganic solid acid catalyst.However, there are some defects in the practical use.A high value-added solid acid catalyst was developed with cheap attapulgite as a carrier.The method of enhancing specific surface area of at-tapulgite and molding method were studied.Complex solid acid catalyst was prepared using the impregnation method and heat dispersion method, respectively.Moreover, catalytic activity on cyclohexanol dehydration reac-tion was investigated with these two types of catalysts .The results show that the specific surface area of attapulg-ite is up to 233.7 m2/g, and the time of cyclohexanol dehydration reaction is shortened from 54 min to 30 min.
