Abstract
Catalytically active materials were obtained by processing the red mud of the Bogorodskoye field for the treatement of gas emissions from carbon monoxide. It was found that that the use of acid leaching followed by precipitation of sparingly soluble compounds with ammonium hydroxide leads to the production of materials with an iron content of 55% by weight according to elemental analysis. The samples were found to have higher specific surface area (154.8–155.7 m 2 /g) and porosity (0.275–0.311 cm 3 /g) and higher catalytic activity in the CO oxidation reaction compared to untreated red mud. It was confirmed that impregnation of the surface of refined products with copper oxide in the amount of 5 % by mass in terms of metal significantly increases the catalytic activity.
期刊介绍：
The Journal "Ekologia i promyshlennost Rossii" («Ecology and Industry of Russia») is aimed to promote acquaintance of the world scientific and technical public and specialists, interested in the problems of the environment protection, with advanced achievements of the science and engineering practice on securing of stable (self-supporting) evolution within the limits of the United Nations accepted recommendations (RIO 92 and RIO+20). A circle of papers includes basic researches and engineering decisions, analytical and methodical operations, reviews on journal subjects. The journal lays special emphasis on methodical elaborations, analytical investigations in the sphere of creating the ecological culture of the population, to the features of ecological education in higher schools of the country for the sake of actualization in specialists'' consciousness of the scientific necessity to know environmental problems of the modern civilization and paths of their settlement. Original papers and investigations of scientists and specialists on separate themes occupy an independent niche of issues under the «Cover story» heading. The journal task is to promote practical implementation of scientific and engineering decisions in the field of decrease of anthropogenic load on the biosphere and environment protection (open lectures, round tables, discussions and so forth). Ecology and Industry of Russia is an informational reference book about the newest developments of the Russian and foreign scientists and the companies realized in Russia, the CIS and Baltic countries, and far-abroad countries. The journal publishes information reports about holding in Russia and abroad the international, all-Russian and regional congresses, conferences, and symposiums related to the journal subjects.
