摘要

This work aims for the development of methodology for the utilization of the waste catalyst from hydrocarbons catalytic cracking process in the production of alumina-silica refractories. This residue was used in substitution of part of conventional raw materials, with the consequent ambient and economic profit. Some formulations were selected based on the chemical and mineralogical compositions of refractory bodies. They were fired in similar temperatures to those used for the production of commercial refractories. The analysis of the technological properties of the bodies revealed that the composition containing 15 wt% of catalyst waste had suitable characteristics. The final product showed technical parameters similar to that of a commercial refractory material.
