“…Очистка отработавших газов от твердых частиц с использованием каталитической нейтрализации реализуется во многом за счет прохождения отработавших газов сквозь пористую проницаемую текстуру каталитического материала, а также в результате догорания. Поэтому применяемые при каталитической очистке материалы должны иметь подходящие физические характеристики: средний приведенный диаметр пор, извилистость и пористость [12]. В связи с этим проведены опытные исследования по изучению связи степени очистки от твердых частиц (δ тч ) отработавших газов СЭУ от диаметра пор (d п ), извилистости (ξ), пористости (П) и содержания ключевого компонента -руды ильменит (С ил ).…”

Burning the liquid fuel in a marine internal combustion engine, which is part of a marine power plant, entails the formation of particulate matter of carbon origin (soot). Particulate matter emitted into the environment cause a significant negative impact on all components of the environment and harm to human health. The use of catalytic purification of exhaust gases using porous permeable catalytic materials can reduce the amount of emitted particles and reduce the burden on the environment. The use of self-propagating high-temperature synthesis in the preparation of porous permeable catalytic materials allows the formation of material properties that provide an acceptable degree of purification of exhaust gases of marine diesel engines from solid particles. The decrease in the concentration of solid particles as a result of the use of catalytic treatment is carried out as a result of the fact that solid particles in the polluted gas passing through the porous structure of used material are retained in the pores and burn out at high temperature. Ensuring high-quality purification of exhaust gas from solid particles depends on a certain pore size, porosity, tortuosity and other properties of the catalytic material. In order to determine the qualitative and quantitative composition of the porous permeable catalytic material used in the purification system, the studies on ilmenite ore-based samples are conducted. Such material, due to the use of ilmenite grinding ore as the basis of the charge, allows us to reduce the cost of catalytic material in comparison with materials that use refined components. The effect of changes in pore diameter, porosity of the catalytic material and the amount of ilmenite ore grinding in the composition of the mixture on the degree of purification of exhaust gases from solid particles is studied. The results are obtained for the first time and described by the least squares method. The results of the study allowed us to determine an acceptable amount of ilmenite ore in the composition of the catalytic material, which permit to reduce the concentration of solid particles in the exhaust gases of marine diesel engines.

Among the methods used, the most effective, from the point of view of the quality of cleaning from the main harmful substances, is catalytic neutralization. The effectiveness of using this method is largely determined by the properties and characteristics of the used catalytic material. Selection of the appropriate composition determines the provision of physical, physico-mechanical and corrosive properties of the used catalytic materials. In this regard, the possibilities of using steel oxide and molding clay as basic components in the charge of the material were studied. In order to reduce the cost of the treatment system, the possibility of replacing valuable expensive components with ore mills of the appropriate composition was considered.As a result of the studies, the optimal qualitative and quantitative composition of the charge of the catalytic material was determined.

A significant negative impact on the environmental components (atmosphere and hydrosphere) is provided by water transport as a result of the use of “heavy” fuels and the lack of effective exhaust gas purification systems. One of the technologically and cost-effective is the cleaning of spent marine power plants using catalytic converters. An optimal degree of purification of exhaust gases from sulfur and nitrogen compounds is ensured by using catalytic materials in porous permeable SHS purification systems.
