Operational Perspectives of Molded Oxide Compositions in Catalytic Neutralization of Toxic Components of Gas Emissions from Industrial Equipment

Resumo

Advances in volumetric thermal expansion in-line with complex physicochemical investigation allowed to introduce and rigorously test novel inexpensive transition metal oxide-based catalysts with varying shapes, which proved valuable against toxic compounds of flue and exhaust gases of various origin. Since the investigated processes can be described with high confidence by well-known diffusion models, the possibility of mathematical prediction of the structure and composition of the proposed catalysts is considered. The target product should be suitable for loading into different types of reactors and have a number of competitive advantages over the known commercial catalysts for gas purification, which are based on noble and rare metals. The possibility of eliminating the chemical, structural and phase history of the starting compounds by means of controlled synthesis to improve the consumer characteristics of the product is investigated. The advantages of the obtained molded catalysts are high activity and selectivity in combination with an increased life cycle and low hydraulic resistance in the catalytic bed.
