The article presents the results of the investigation of catalytic cracking process of crude oil in a distillation column, under atmospheric pressure, the active component of the catalyst being type Y zeolite. The process was carried out under the conditions of a new technology, called ''aerosol nanocatalysis.'' A schematic diagram of the laboratory installation is described and comparison of the experimental data with thermal cracking processes is made, and the expected technical and economic indicators of the new and existing industrial technologies are compared. It is shown that the use of zeolite-containing catalyst (type Y) leads to increased yield of light oil products by 48-85% by weight compared to thermal cracking. The technology of aerosol nanocatalysis is promising as it is energy and resource-saving process.

Продовжується вивчення процесу конверсiї вугiлля в синтез-газ в умовах аерозольного нанокаталiзу та обґрунтовано очiкуванi переваги майбутньої промислової технологiї. До переваг можна вiднести можливiсть змiнювати швидкiсть реакцiї шляхом впливу на iнтенсивнiсть механохiмiчної активацiї каталiзатору. Дослiдження процесу проводилось в реакторi, де механохiмiчна активацiя здiйснюється шляхом обертання каталiтичної системи. Вплив iнтенсивностi активацiї на хiмiчнi реакцiї в умовах аерозольного нанокаталiзу ранiше вже був доведений для реакторiв iз псевдозрiдженим та вiброзрiдженим шаром каталiтичної системи. Попереднi дослiдження виявили, що механохiмiчна активацiя впливає на склад продуктiв конверсiї, а саме на спiввiдношення СО:Н 2. Це дозволить в майбутньому швидко переорiєнтовувати виробництва синтез-газу пiд кон'юнктуру ринку органiчних продуктiв. Результати дослiдження показали, що при температурi 750 °С, 1 атм, iнтенсивностi МХА 2-4 об/с i надлишку вугiлля (С:

The influence of bioethanol content and parameters of the cavitation field on the quality indicators of motor gasolines: volatility and octane number is studied. Studying the effect of bioethanol and cavitation treatment of bioethanol-gasoline mixture will make it possible to produce automotive fuels for different climatic zones, or winter (summer) versions of gasolines. The use of bioethanol and cavitation treatment of a bioethanol-gasoline mixture affect the fractional composition of motor gasoline and its volatility. The optimal content of the biocomponent, at which there is an increase in the volatility of gasoline, is established Also the results of the octane number change are presented depending on the intensity of cavitation treatment for gas condensate with the addition of bioethanol. The influence of bioethanol content on the increase in octane number during cavitation treatment is determined. It is found that the introduction of bioethanol into the composition of gasoline leads to an improvement in its volatility. In this case, cavitation treatment makes it possible to obtain a mixture resistant to delamination. The addition of bioethanol leads to an adequate increase in light fractions during mechanical mixing and to a change in the fractional composition of the bioethanol-gasoline mixture during cavitation treatment. The addition of bioethanol in amounts up to 10% leads to a decrease in the saturated vapor pressure during cavitation treatment of bioethanol-gasoline mixtures, and an increase in the bioethanol content up to 20% leads to an increase in the saturated vapor pressure, which is explained by a change in the chemical composition of fuel components in comparison with the mechanical method of preparing mixtures. By cavitation treatment it is possible to change the fractional composition, the pressure of saturated vapors and the volatility of bioethanol-gasoline mixtures, making cavitation a promising energy-saving process for the production of gasoline for various climatic conditions

petroleum processing using the natural catalysts might contribute to better competitiveness of domestic refineries in the world market. We shall consider this task by employing a technology of aerosol nanocatalysis. Literature review and problem statementIt is widely known that zeolite is an additive in the composition of the aluminosilicate catalyst of cracking. It allows increasing activity, selectivity, adsorptivity and thermostability of structure. However, the stability of these catalysts at thermal and thermo steaming treatment changes in line with the stability of zeolite [2].The Omsk refinery (Russia) operates catalytic cracking plants, which employ a series of catalysts -microspherical zeolite catalyst. The studies that started in 2004 have demonstrated the effectiveness of catalysts based on the ultra-stable zeolite of a series "Lux". These catalysts are prepared separately and they have complex composition. The following components are included into its composition: stabilized zeolite of the type Y in form HREE (REE are the rare-earth elements), amorphous dispersed alumosilicate
