Abstract:
The formation of highly imperfect γ-Al2O3 oxide prepared by calcining pseuodoboehmite and plasticized by organic acids was studied. The nature of the organic acid-aluminum hydroxide plasticizer was found to substantially influence the degree of γ-Al2O3 structure imperfection estimated qualitatively as the difference between the X-ray structural density and effective density with respect to helium and aluminum oxide. A high degree of imperfection caused an increase in the intensity of the absorption band at 3775 cm-1 corresponding to OH groups localized on five-coordinate Al3+ and the concentration of Lewis acid centers. The adsorption and catalytic properties of systems based on these carriers were studied.
