This work presents the synthesis and comprehensive investigation of chromium-free catalysts based on γ-Al2O3, modified with magnesium oxide (MgO) and copper oxide (CuO), intended for application in thermocatalytic fuel combustion processes under fluidized bed conditions. The preparation technology was optimized by selecting impregnation time, drying, and calcination conditions. X-ray phase analysis confirmed the formation of a spinel solid solution structure MgxAl3-xO4, which contributes to the strengthening of the carrier. Subsequent introduction of CuO into the strengthened carrier in amounts of 2–5 wt% significantly enhanced catalytic activity, reducing the temperature for achieving 50 % CO conversion to levels comparable with the industrial deep oxidation catalyst DOC. Under vibro-fluidized bed conditions and during combustion of real sewage sludge, the developed catalysts demonstrated a high burnout degree (96–97 %) and low emissions of harmful substances (CO, NOx, CH4), comparable to industrial analogs. The obtained results indicate the promise of the proposed approach for the development of effective and environmentally safe catalysts for fuel combustion in fluidized bed.
