摘要：

Sulfated zirconia catalysts active in the isomerization of n-butane have been synthesized by sulfating crystalline monoclinic and cubic zirconia supports precalcined at 700 degrees C. Strong acceptor sites capable of ionizing chlorobenzene have been observed on all active catalysts irrespective of the crystalline structure. A simple instrumental technique based on the chlorobenzene adsorption has been suggested for probing sulfated zirconia catalysts. (C) 2000 Elsevier Science B.V. All rights reserved.
