Mathematical Modelling And Optimisation Of The Reactor For The Esterification Process Of Safflower Oil With N-Butyl Alcohol, Sadritdin Makhamatdinovich Turabdjanov Academician, Hasan Sadriddin Ugli Fozilov, Ozoda Bakhronovna Axmedova, Sadriddin Fayzullayevich Fozilov

Technical science and innovation

This study addresses the mathematical modelling and optimisation of a reactor for the esterification of safflower oil with n-butyl alcohol. To improve process controllability and reduce the need for numerous pilot-scale trials, an ideal-mixing continuous stirred-tank reactor (CSTR) model was adopted. Incorporating reaction kinetics, the effect of contact time on the relative viscosity of the product mixture was analysed. The modelling results indicate that achieving an acceptable degree of feedstock conversion is difficult when a single ideal-mixing reactor is used. Therefore, a CSTR cascade was proposed, and the configuration with N = 2 reactors was selected as the most appropriate …

Approach Formula To Increase Energy Efficiency Of Internal Combustion Engines In The “Green Economy” And Impact On The Natural Ecosystem, Zakirjon Ergashevich Musabekov, Hilola Zokir Qizi Uralova, Sayyodbek Ilxomjon O‘G‘Li Abdullajonov

Technical science and innovation

This article discusses, analyzes, and proposes solutions for the role of internal combustion engines in forming a "green economy", as well as ways to replace or modernize them. The relationship between internal combustion engines and the "green economy," as well as their energy efficiency and impact on natural ecosystems, is a crucial and urgent issue. These engines primarily generate energy through the combustion of petroleum-based fuels such as gasoline and diesel. However, this process releases harmful gases into the atmosphere, contributing to environmental degradation. The green economy is an economic model designed to protect the environment, ensure the efficient management …

Study Of Technological Parameters On Catalytic Hydroisomerisation Of Aromatic Hydrocarbons Into Alkyl Naphthenic Hydrocarbons, Habibullaeva Mirzaxmatovna Ra'no, Nodira Turobjonovna Torayeva, Temurbek Z. Daminov, Murod Azimovich Eshmukhamedov

Technical science and innovation

The article presents experimental results of the catalytic hydroisomerization of aromatic hydrocarbons into alkyl naphthenic hydrocarbons. Aluminum col-molybdenum with silicon oxides has been studied as a catalytic system, which imparts acidic properties to the catalytic system and stimulates isomerization.

The dehydrogenation reaction of cyclohexane has been studied, which occurs on the active surface of one of the metal oxides to cyclohexene, then the resulting cycloolefin diffuses to the acidic active center - aluminosilicate, where skeletal isomerization occurs and then the isomerized cycloolefin again returns to the active center of the surface of the catalytic system, where it is hydrogenated to …

Methods Of Improving Complex Cleaning Of Sand Plugs In Khodjaobad Underground Gas Wells, Abdulaziz Murodov, Muhriddin Muydinov, Saidaziz Khabibullaev, Aziz Abidov

Technical science and innovation

The purpose of the study is to develop recommendations for improving the methods of cleaning complex sand plugs in wells of underground gas storage. To organize the correct and efficient use of underground gas storage, the bottom of wells must be kept clean. The article develops recommendations on the use of optimal methods for cleaning wells from complex sand jams on the example of Khujabad UGS. In addition, recommendations were developed for the operation of production wells in the horizons of the XX-XXI-XXII underground gas storage of Khujabad
