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