Results of research of influence of conditions into thermal processing of hydrogel of Al(OH)3 in an electromagnetic field of the microwave oven-range on formation of textural characteristics γ-Al2O3-carrier of active weight of potential heterogeneous catalysts of the put type are submitted. The basic opportunity of use of alumina Gandjas of aluminous combine is shown as the predecessor of alumina oxide forming carrier. It has been established that in the said conditions of heat treatment Al(OH)3 in a field of the microwave oven there is a structurization alumina oxide the matrix characterized by the advanced surface and porosity with to prevalent pores of medium-size to obtain catalysts of this type.
