Claims (1)

Предложен катализатор окисления вредных выбросов отходящих газов промышленных производств, сжигания топлив на основе смешанных оксидов переходных и редкоземельных элементов со структурой перовскита, содержащий дополнительно оксид алюминия. Катализатор также может содержать в избытке либо оксиды переходных элементов, либо оксиды редкоземельных элементов, либо одновременно и те и другие оксиды, отличающиеся от перовскита своей структурой. Предложены также способы получения катализатора, включающие стадии синтеза порошкообразных перовскитов путем диспергирования растворов в дуговой плазме либо механической обработки кислородсодержащих соединений редкоземельных и переходных элементов. Полученный катализатор отличается повышенной термостабильностью и устойчивостью к коррозии в агрессивных средах.A catalyst for the oxidation of harmful emissions from industrial exhaust gases, the combustion of fuels based on mixed oxides of transition and rare-earth elements with a perovskite structure, containing additional aluminum oxide is proposed. The catalyst may also contain in excess either oxides of transition elements or oxides of rare-earth elements, or at the same time those and other oxides that differ from perovskite in their structure. Proposed methods for the preparation of the catalyst, including the stage of the synthesis of powdered perovskites by dispersing solutions in arc plasma or by mechanical treatment of oxygen-containing compounds of rare-earth and transition elements. The resulting catalyst is characterized by high thermal stability and corrosion resistance in aggressive environments.
