摘要
Cr(CO)(6)/Al2O3 samples were prepared in a fluidized bed reactor by vapour phase adsorption of chromium hexacarbonyl under nitrogen flow. The preparation of the samples were followed by diffuse reflectance IR spectroscopy and the chromium content was determined by EDXRF. Deposition and pulse techniques were used to vaporize the hexacarbonyl on the alumina surface. The pulse technique proved to be very effective when higher chromium contents were desired. The temperature of the calcination (500 degrees C/300 degrees C) also had a significant effect on the amount of chromium adsorbed. (C) 1998 Elsevier Science B.V. All rights reserved.
