IMPROVING ENVIRONMENTAL SAFETY THROUGH THE USE OF SLAG MATERIAL AND SPENT CATALYST IN THE PRODUCTION OF CERAMIC BRICKS ON THE BASIS OF BEIDELLITE CLAY

Abstract

The efficiency of all industries should be assessed from the point of view of the balance between the weight of the main product and the volume of generated industrial waste, therefore, the aim of the present work is ─ to the receiving using the tonnage of waste fuel and energy complex of ash and slag material and waste chemistry, spent catalyst, one of the most material-intensive products of the national economy ─ a ce-ramic brick on the basis of beidellite clay. Fuel and energy complex is one of the main "pollutants" of the en-vironment. These are emissions into the atmosphere (48% of all emissions into the atmosphere), wastewater discharges (36% of all discharges), as well as the formation of solid waste (30% of all solid pollutants). The basic technical properties of ash and slag material used as autosites and burnable additive and spent cata-lyst, is used as aluminum-containing autosites to increase marochetti brick. Studies have shown that the spent catalyst IM-2201 Novokuibyshevsk petrochemical plant refers to nanotechnology raw materials. The effect of the introduction of nanoscale particles is fundamentally expressed in the fact that not only an additional in-terface appears in the system, but also a carrier of quantum mechanical manifestations. The presence of na-noscale particles in the system increases the volume of adsorption and chemisorption bound water and re-duces the volume of capillary-bound and free water, which leads to an increase in the plasticity of the ceram-ic mass and strength parameters. Ceramic brick with high physical and mechanical properties is obtained on the basis of beidellite clay with the use of ash-slag material and spent catalyst. Innovative proposals for the use of waste fuel and energy complex and petrochemical industry in the production of ceramic bricks, the novelty of which is confirmed by two Patents of the Russian Federation.
