In this work, a possibility of using hydraulic fracturing proppants (HFP) as supports for deep oxidation catalysts, employed in the fluidized bed catalytic combustion, was considered. Two methods based on leaching with alkali solution were used to increase a specific surface area of HFP. The samples were characterized by physico-chemical methods (XPS, XRD, low-temperature nitrogen adsorption). CuCrcontaining catalysts, based on HFP and obtained by the wet-impregnation method, and industrial catalysts were tested in the process of combustion brown coal in fluidized bed. It was shown that catalysts based on HFP allow us to reach a high degree of burnout (95%) which typical for industrial catalysts and higher than in the case when using an inert material (70%)
