摘要

研究了利用玻璃纤维载体催化还原脱除工业废气中氮氧化物的方法。有人指出，这种技术可以在中等温度下减少氮氧化物并将一氧化碳和碳氢化合物氧化为安全化合物，而不需要额外的试剂(氨、尿素)。结果表明，以波纹金属网为结构的催化块具有最高的催化活性，而最佳载体是微晶织物。结果表明，所述催化剂具有高内部质量交换率、低水力阻力、高渗透性以及在含尘流中应用的可能性等特点，在处理各种烟气和废气方面具有广阔的应用前景。

Fibreglass Catalysts for the Removal of Nitrogen Oxides from Industrial Exhaust Gases

A method for removing nitrogen oxides from industrial of exhaust gases by catalytic reduction using fibreglass carriers was studied. It was noted that this know-how reduces nitrogen oxides and oxidizes carbon monoxide and hydrocarbons to safe compounds at moderate temperatures without additional reagents (ammonia, urea). It was proven that catalytic blocks structured with corrugated flat metal meshes provide the highest catalyst activity, and the best carrier is macosatin fabric. It was concluded that the described catalysts are characterized by high internal mass exchange rate in combination with low hydraulic resistance, high permeability, and the possibility of being used in dusty flows, which makes them very promising for treating various flue and exhaust gases.

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.
