The production of remainders is inevitable that constitute the last link of any industrial activity. The increase in the volume of industrial wastes, the simultaneous diminution of the spaces of disposition of remainders, as well as all the problems associated with the contamination that this implies, are urgency subjects that demand the attention of scientists and technologists.  They have propused numerous changes in the productive processes with the denominated clean technologies and minimización, that tend on the one hand to reduce in origin the generation of remainders, and by the other have been applied to reuse transforming them in by products and raw material of other industries. The reusability consists of redriven the residual materials towards new processes of production, instead of destining them to the current of discardings. In this work the possibility of use of diverse industrial waste like materials of support in the production of catalysts studies. This work is innovating in the area of the catalysis, it is in one first facet of study and the use of the remainders without treatment has settled down subsequent to its remainder. The studied industrial remainders are: * exhausted resulting catalysts of the process of treatment of petroleum (K1) * red mud of high furnace of iron and steel industry (K2) * ash of sunflower seeds (waste of boiler of oil industry) (K3) * sand of moulding of smelting industries (K4) * ash of bottom of a combustion furnace of an energy power station (K5) * flying ash of washing of combustion furnace chimneys (K6)
