IMPROVING THE ENERGY EFFICIENCY OF LOW-RISE RESIDENTIAL BUILDINGS

Khalimov Khabibullo Bakhtiyorjon Ugli

The most promising direction of rational use and saving of fuel and energy resources is related to energy saving in various spheres of economic activity. More than a quarter of the energy saving potential is concentrated in the housing and utility industry, and more than a third in construction and industry. The main number of buildings in operation in our country are non-energy-efficient constructions made of prefabricated reinforced concrete and local materials, whose thermal performance deteriorates during operation due to poor quality or improper operation. In the article, the issues of improving the energy efficiency of low-rise residential buildings were studied in detail, suggestions and conclusions were given.

EXPERIMENTAL ANALYSIS OF MASS EXCHANGE PROCESSES IN THE CONTACT ELEMENT GENERATING DEVICE

Nasimbek Ergashev Axmadjonovich, Abdumannonova Мuzayyamxon Muzaffarjon Qizi

Cleaning of harmful dust and gases generated in technological processes today is one of the important tasks of this day. Therefore, the main working factors affecting the cleaning process were determined in the experimental model of the newly developed contact element accumulative flow generator. The gas velocity, gas and liquid consumption in the apparatus, the length of the liquid film and the working surface were determined based on experiments

OXIDATIVE DIMERIZATION OF METHANE: KINETICS OF THE REACTION

Safarova Mavjuda Jomurodovna, Normurot Ibodullayevich Fayzullaev

In this article, the textural properties of catalysts and the process of catalytic dimerization of methane using catalysts based on salts of alkali and alkaline-earth metals containing molybdenum and manganese oxides were studied. It was found that the catalytic conversion of methane takes place on the surface of a catalyst that adsorbs oxygen to form an active complex [ZOCH3]. It has been shown that the catalytic conversion of methane can be carried out simultaneously with the formation of ethane and ethylene. At the same time, the percentage of ethylene in the free volume of the reactor increases compared to ethane, which helps the reaction of ethylene formation without oxygen and catalyst. Phenomenological equations for the kinetics of the catalytic reaction of methane dimerization are formulated and rate constants and Arrhenius parameters are calculated.

BIOGEOCHEMICAL PROPERTIES OF SALINE GRASSLAND SOILS AND SALT MARSHES AND THE BENEFITS OF USING MICRO FERTILIZERS

Sobirov Anvarjon Odilovich

The elemental composition of soils and the biogeochemical processes taking place in them are shown in the article. Opinions are given on the composition of microelements of saline meadow soils and salt marshes and the biophilicity of these elements. Microfertilizers are substances that contain microelements and are used in small amounts for the normal growth of plants. The presence of most of the elements in D.I. Mendeleev's periodic system of elements in the soil, plants and living organisms. However, the measurement of their quantity is about making a very wide range n "10-3- n "10-5 and even n "10-9- n "10-10 %.
