An actual problem of the alcohol industry development is the expansion of the raw material base through the use of new, cheaper types of carbohydrate sources. Recently, glucose-fructose syrup has been of increasing interest to producers of ethanol. Among the producers of craft drinks, in particular rum-based drinks, cane molasses is in increasing demand. The article presents the technological aspects of the fermentation process of nonconventional sugar-containing raw materials on the example of glucose-fructose syrup and cane molasses in ethanol by different yeast strains. It is determined that glucose-fructose syrup and cane molasses are raw materials depleted of nitrogen, phosphorus and growth substances necessary for the yeast activity. To improve the technological properties of raw materials in the molasses, nitrogen, phosphorus nutrition and corn extract as a growth substance shall be added to a mash. Glucose-fructose syrup is of pH 3.68 and of acidity 0.12, which negatively affects the fermentation. It is established that in order to create optimal living conditions for yeast, it is necessary to add substances to the glucose-fructose syrup that will contribute to the safety of development and prevent the pH 3.5. It was determined that the alcohol yield from 1 ton of glucose-fructose syrup is 31.0 dal, from 1 ton of cane molasses is 24.0 dal on the yeast 46ED and 22 dal on the TegaYeast without the use of growth substances and vitamins necessary for the reproduction of yeast biomass. Under conditions of improving the technological properties of the mash from the glucose-fructose syrup and cane molasses by adding biologically active substances promoting the synthesis of yeast biomass, the ethanol content in the fermented mashes increases up to 11.9 12% vol.

Among the relevant for the modern pharmacy problems, there is a need for the rational complex use of known medicinal plants, as well as the search for new sources of natural biologically active compounds in order to expand the list of official medicinal plants and raw material base. Species of genus Geum L. contain a number of biological active substances and are promising sources of raw materials for the production of antimicrobial, astringent, anti-inflammatory, and hemostatic medicines. Pharmacological activity of these plants results from their multi-component chemical composition, including tannins, flavonoids, macro- and microelements and other compounds. The aim of thе study was to compare the elemental composition of herb and rhizomes with roots of G. urbanum L., G. aleppicum Jacq. and G. rivale L. of Ukrainian flora. The objects of the study were the samples of herb and rhizome with roots of G. urbanum L., G. aleppicum Jacq. and G. rivale L. (dried raw materials) which were collected in the Kharkiv region, Ruski Tishki village, in June-August 2018–2019. The determination of the qualitative composition and quantitative content of elements was carried out by atomic absorption spectroscopy with atomization in an air-acetylene flame using a spectrometer CAS 120 («Selmi», Sumy, Ukraine). In the studied samples, 19 elements were determined, including 5 macroelements and 14 microelements. The data about accumulation of elements in investigated herb of G. urbanum L., G. aleppicum Jacq., G. rivale L. can be arranged in descending order as follows: K > Ca > Si > Mg > P > Fe > Al > Na > Sr > Zn, and in rhizomes with roots as follows – K > Si > Ca > Mg > Fe > P > Al > Na > Sr > Zn. The content of toxic elements such as cobalt, cadmium, arsenic, and mercury was within the permissible limits for plant raw materials and food. For the first time, a comparative study of the macro- and microelement composition in herb and rhizomes with roots of G. urbanum L., G. aleppicum Jacq. and G. rivale L. has been carried out.

To expand the raw material base of medicinal plant raw materials, a promising area of research is the study of additional types of raw materials that can be harvested from already used medicinal and food plants. Given the complexity of harvesting alder seeds, researchers are interested in the leaves of this plant, a wide range of biologically active substances that cause anti-inflammatory, astringent and antioxidant effects. The first stage of standardization of raw materials is the definition of morphologically significant features, based on the generalization of which the section "External features" is developed. The analysis of morphological features of freshly harvested, dried and frozen leaves of gray alder (Alnus incana Moench) and black alder (A. glutinosa Gaerth) harvested from wild plants in mixed forests of the Moscow region revealed diagnostically significant features and found that the method of conservation does not affect the occurrence of the identified features. Since it is planned to use both types of alder for the preparation of a new type of raw material "Alder leaves", a generalized formulation is proposed for raw materials that are a mixture of species.

To use effectively internal raw material base, JSC “Ural Steel” accomplished I category major overhaul of the blast furnace No. 2. The main purpose of the overhaul was to design a rational profile which could ensure an ability to operate with a charge containing 95 % of Mikhailovskii GOK (mining and concentrating plant) pellets having basicity of 0.5 by CaO/SiO2. The blast furnace No. 2 having useful volume of 1232 m3, was constructed by design of Danieli Corus, the Netherlands, and was blown in on December 30, 2020. In the process of guarantee tests, step-by-step increase of Mikhailovskii GOK pellets (Fetotal = 60.5 %, CaO/SiO2 = 0.5) content in the charge iron ore part was being accomplished from 55 to 95.1%. Charging of the blend containing pellets in the amount of 55% of iron ore part, was done by charging system 4OOCC + 1COOCC (Ore - Coke) with filling level 1.5 m. Under conditions of pellets part increase in the blend, the charging system was changed to decrease their content at the periphery, to increase it in the ore ridge zone and make it intermediate between periphery and the ore ridge. At the pellets share in the iron ore raw materials 0.75 the charging system was used as the following: 3OOCC + 1COOC + 1COOCC, while at the content 95.1% the following charging system was used: 2COOC + 2COOC + 1COOCC. It was noted that in the period of guarantee tests the furnace running was smooth. The average silicon content in the hot metal was 0.70% at the standard deviation 0.666. Sulfur content in the hot metal did not exceed 0.024%, the blowing and natural gas consumption figures were 2100 m3/min and 11000 m3/min correspondently, oxygen content in the blowing 26.5%, hot blowing and top smoke pressure figures were 226.5 and 109.8 KPa correspondently. The productivity of the furnace was reached as high as 2358 t/day at the specific coke rate 433 kg/t of hot metal. After guarantee tests completion, the pellets content in the iron ore part was decreased gradually from 95 down to 50%. The decreasing was made by 5% in every 6 hours of operation. Application of the mastered technology of the blast furnace No. 2 with the increased share of pellets will enable to stably supply the blast furnaces No. 1, 3 and 4 by iron ore raw materials in the proportion of 30-35% of pellets and 65-70% of sinter.

BACKGROUND: A possible reduction in stocks of medicinal plant raw materials of Thymus serpyllum L. and Thymus vulgaris L. leads to the need to expand the raw material base of the official medicinal plants with using of endemic species of the flora of Kazakhstan, in particular, Thymus rasitatus Klokov, and Thymus eremita Klokov. AIM: The aim of the study was to study the possibility of using 70% ethanol extracts of T. rasitatus and T. eremita as antimicrobial agents. MATERIALS AND METHODS: The aerial parts of T. rasitatus and T. eremita were extracted with 70% ethanol using ultrasound assisted extraction. The qualitative and quantitative analyses of the 70% ethanol extracts were determined using the liquid chromatography-detection-ESI-mass spectrometry-(MS)/MS technique. The study of the antimicrobial activity of these extracts was performed for eight strains of Gram-positive bacteria, six strains of Gram-negative bacteria, and four cultures of fungi. RESULTS: Chromatographic analysis of hydroalcoholic extracts of both investigated Thymus species showed very similar phenolic compounds composition. In both cases, the major components are luteolin-7-O-glucoside and rosmarinic acid. About 70% ethanol extracts of T. rasitatus and T. eremita have a broad spectrum of antimicrobial activity, exhibit the bactericidal or bacteriostatic activity against all tested bacteria and fungi at concentration range of 0.0195–20 mg/ml, but differ in their potency against tested strains of microorganisms. CONCLUSION: About 70% ethanol extracts of T. rasitatus and T. eremita, endemic plants in the flora of Kazakhstan, can be considered as potential drugs with a wide spectrum of antimicrobial activity. The results of chromatographic analysis could be used for drug standardization.

Increasing Demand

The increasing demand for zinc and a range of zinc-related metals (for example: lead; indium; tin; cadmium; and copper) in the Russian Federation cannot be satisfied by the existing production plants due to the lack of raw materials. At the same time, ferrous and non-ferrous metallurgy and the chemical industry have accumulated hundreds of millions of tons of zinc wastes (falling into the hazard categories 2 to 4), the processing of which could not only make up the raw material base, but also improve the environmental situation. In the world, over 85% of ferrous dust is recycled using the Waelz process. The Waeltz process is used for distilling separation of elements under reducing conditions. In this study, a block diagram for production of the following elements from industrial wastes is proposed: zinc, cadmium and indium in form of massive metals; zinc and indium in the form of fine powders; and clinker as a raw material for cement production. The technical and scientific details of this new process have been patented in the Russian Federation and abroad. For the first time, the following operations have been implemented with the use of large-sized Waelz kilns: vapour-oxidized Waeltz treatment of polymetallic wastes; recycling of heat from gases and solid products with generation of process fumes; and implementation of alternative flux (dolomite) and alternative fuel (petroleum coke). Keywords: Waelz process, industrial wastes, heat recycling, vapour-oxidized Waelz processing
