This invention relates to a process wherein improved production of catalysts is made possible according to an evolutionary method. The principles of mutation and crossing of catalyst components and determination of performance parameters of the mixed catalysts used here are carried out in 5 to 50 catalyst generations in such way that two mixed catalysts are selected from the same generation in crossing, and at least one selected component is exchanged between the two, and in mutation of a selected mixed catalyst, a selected component from a catalyst mixture is introduced into the catalyst or, if already present in it, it is removed from the catalyst. The selection is made in all cases by using random generators with a uniform distribution. The same procedure is used for the gas flow composition, the temperature and the space velocity as the other performance parameters.

Process for production of new catalysts using an evolutionary process

The invention refers to a method for removing traces of hydrocarbons, particularly propane, from gas flows. The conversion of hydrocarbons into carbon oxides is achieved by loading suitable carrier materials, such as e.g. TiOor AlO, with ruthenium as active component, possibly doping them with one or more further element(s), and subsequently calcining and/or reducing them at an increased temperature. By means of these catalysts, and at 20 to 150&#xb0; C. and while adding molecular oxygen, hydrocarbons, particularly propane, in concentrations ranging from 0.1 to 2,000 ppm are oxidized.
