This work aimed the development of methodology for the utilization of the residue of catalyst from of hydro-carbons catalytic cracking process in the production of alumina-silica refractory. This residue was used in substitution of part of conventional raw materials, with the consequent ambient and economic profit. It was selected some formulations based on the chemical and mineralogical compositions of refractory masses. They were fired in similar temperatures to the ones used for production of commercial refractories. The analysis of the technological properties of the formulations proposed, defined that the composition that contained 15% wt of catalyst waste got the best characteristics. The final product showed technical parameters similar to the ones of commercial refractory material.
