The organic part of bituminous Sands (BS) is a chemical raw material of complex and unstable composition. The physical and chemical properties and composition of this raw material depend on the BS Deposit, the method of separation of the organic part, methods and equipment for analysis. The organic component-natural bitumen-is an oil dispersed system, the dispersed phase of which is formed by high – molecular components-resins and asphaltenes; the dispersed medium is made up of lighter hydrocarbons. It was found that traces of tungsten oxide (V), primary and secondary alcohols, and esters were found in the bituminous rock of the Deposit. It was found that natural bitumen extracted from BS contains saturated hydrocarbons: linear: n-heptane, n-decane and cycloparaffins: 1-phenyldodecane, methylcyclohexane, various primary and secondary alcohols, ketone and esters.

From the pyrolysis process, biochar is a carbon rich and recalcitrant organic material with potential for long term carbon sequestration because of its aromatic structure. However, the physical and chemical properties of the biochar vary due to the diversity of raw material and the conditions of production. The present study aimed to evaluate the biochar from the sugarcane bagasse at different temperatures and under two conditions of pyrolysis. The biochar was produced at two final temperatures 200°C (1 hour); 250°C (1h) and 250°C (2h), with pyrolysis of an oxidizing and non-oxidizing atmosphere for both. PH, cation exchange capacity (CTC), carbon content (C), Nitrogen (N), hydrogen (H), H:C, C:N and ash ratios were evaluated. The contents of C, H, N and the atomic ratios H:C and C:N were higher in Biochar produced in a non-oxidizing atmosphere (BNO). However, the content of ash, pH and CTC were higher in Biochar produced in oxidizing atmospheres (BO). One can conclude the direct influence of the pyrolysis condition.

The Impact

In connection with the development of copper and molybdenum production in Armenia, it becomes necessary to develop a technology for processing the slags of the functioning metallurgical plants to extract valuable metals from these slags. It concerns the copper slags of Alaverdi Copper-Smelting Plant with a content of FeO ~50  % and the molybdenum slags of Yerevan “Pure Iron” Plant with a content of SiO2 ~80  %. These slags are obtained at high temperatures (with FeO·SiO2 , CaO·SiO2 , Fe3 O4 ) and, therefore, they are less active to be used later. Meanwhile, the mentioned slags are rich in iron and silicon oxides and can serve as a cheap raw material for producing iron silicides. The iron silicides can be used in micro- and nanoelectronics, as well as in metallurgy as an alloying additive in the production of steels of special physical and chemical properties. The production of such valuable silicides from an inexpensive raw material is important for Republic of Armenia and is of not only economic, but also ecological significance. To obtain iron silicides, a method of combined aluminothermal reduction of primarily mechanoactivated copper and molybdenum slags is proposed. The preliminary mechanoactivation allows to purposefully affect the structure of the reaction mixture and parameters of the self-propagating high-temperature synthesis (SHS), thus ensuring the possibility of regulating the structure and phase composition of the synthesized silicides. This work considers issues on the impact of transformation and phase formation on the morphology of slags of copper and molybdenum production in the functioning Armenian metallurgical plants at mechanochemical activation by the method of fine grinding in a vibromill. It is shown that at fine grinding (up to 10  mcm), the slags, containing small-reactivity complex compounds of iron and silicon (fayalite, magnetite, quarzite) undergo profound chemical changes, transforming into amorphous oxides. The obtained activated oxides can serve as a raw material for producing iron- and silicon-containing alloys – iron silicides.

Introduction. The production of gluten-free food products, including alcohol-free beverages, is an urgent task for Russian food industry. Buckwheat malt has a great raw material potential, because it consists rutin, which can give the final product some useful functional properties. Aromatic raw materials improve the sensory characteristics of beverages and increase their nutritional value. Study objects and methods. Kvass is a traditional Russian bread juice. To prepare gluten-free kvass, we used light and scalding buckwheat malt and water infusions of barberry, juniper, leaves of garden currant, and lemon balm grass. The wort was prepared by infusion and fermented with bottom beer yeast Saflager W-34/70. Then it was blended with infusions of plant materials. Sensory and physical and chemical properties of kvass were determined by standard methods. Antioxidant activity of the beverages was assessed by using DPPH radical scavenging method. Results and discussion. All samples met the state standard requirements for kvass by sensory, physical, and chemical characteristics. The drinks obtained from the scalding malt were well-fermented and achieved better tasting ratings compared to those from the light malt. The control sample, which contained no aromatic raw materials, received the lowest scores for taste and aroma. The kvass blended with infusions of barberry and garden currant had the best results. The infusions increased the shelf life of the kvass from 7 days (control) to 12 (barberry), 14 (juniper), and 16 (currant). All samples of kvass demonstrated antioxidant activity, the beverage with infusion of garden currant leaves showing the best results (≤ 80%). Antiradical activity was established for the samples blended with barberry and currant infusions. Conclusion. light and scalding buckwheat malt can be used to prepare gluten-free kvass. Blending buckwheat kvass with infusions of aromatic raw materials increased the shelf life of the beverages, improved their taste, aroma, and antioxidant activity (except the sample with infusions of juniper), and gave them antiradical properties.

The main environmental issue associated with compost production is the production of a liquid leachate. Leachate from municipal wastes contains carbon, nitrogen, phosphorus, potassium and trace elements that can be used as nutrients by plants. The advantages of the use of organic wastes such as compost leachate as fertilizers are evident. Their use would reduce the consumption of commercial fertilizers, which need, with their production, high cost and energy. This work aims to determine the physical and chemical properties of a specific leachate with a variable composition, collected from the composting line of a mechanical and biological treatment facility. The goal is to assess if the leachates can be used as a potential source for fertilizers, and thus develop and design a sequence of processes which could effectively convert the leachates to commercial fertilizers according to the requirements of the proposal of regulation of the European Parliament of 2016 for fertilizers. Preliminary results show that the leachate samples qualitatively meet the requirements established for the composition of commercial fertilizers, especially organo-mineral fertilizers. Furthermore, there is no production cost of leachate as a raw material. The results show that the leachate is characterized by manageable concentrations of heavy metals which can be removed by adsorption processes, and it presents suitable amounts of organic carbon after a water removal procedure. However, the establishment of the conditions for suitable conversion processes are still under investigation considering the high composition variability due to factors like storage and environmental conditions.

The effect of alkali metal (Li, Na, K) incorporation on the morphology and water vapor uptake properties of mesoporous Al2O3 has been studied. The modification of the raw material, pseudoboehmite, represented a mixture of low-temperature phases (γ + η + χ)-Al2O3, and has been done at low-temperature that does not change the phase ratio. A decrease in specific surface values and an average pores size increase were observed as a result of the introduction of metal cations by impregnation and subsequent thermal treatment. The influence of the content of the modifying metal on the adsorption ability of the obtained samples in relation to water vapours has been studied. It has been established that alkaline modification Al2O3 with the lithium cations did not result in adsorption ability improvement, whereas samples that were modified with sodium or potassium in the amount of 1.2 weight % and 2.6 weight %, respectively, possess a higher equilibrium capacity (by ~40%), as compared to that of the initial sample (Al2O3), and a sufficiently high adsorption rate.
