The presence of hydrocarbons in industrial processes as well as their emission to theatmosphere is a problem that can be treated by catalytic oxidation processes.The developed catalysts are usually produced in powder form but are difficult to use in realconditions due to the high flow rates that generate pressure drop problems. To minimize thisproblem, monolithic structures are used in which the active material is deposited. Thesestructured materials also have the advantages of better heat transfer and greater chemical andmechanical stability.In addition, the use of waste to produce new materials is an alternative to reduce theenvironmental impact.In this work, cobalt catalysts were developed using eggshell supported monolithicstructures, and their performance in the oxidation of toluene under different concentrations ofreagents in the feed stream was studied
