Popis:	The dependence of the porous structure of Pt-Cr/AL2O3 catalysts on the nature of chromium-containing compounds used as modifiers and the manner of their introduction has been investigated. It is established that the use of acid reagents leads to “erosion” of the support and the formation of a chromium oxide phase of a higher density. If gaseous components are evolved during modification and calcination of the samples, the porous structure changes to a lesser degree.
