Assessment of inhibitive property of sulfur as a filler of polymer materials with a view to reduce technogenic impact on ecology
© National Academy of Sciences of the Republic of Kazakhstan, 2017. According to modern representations bitumen polymer compositions are dispersions of polymers with bitumens. The important stage of creation of durable insulating materials is their inhibition in consequence of oxidation processes in conditions of their application. In this connection the most acceptable substance is sulfurcontaining compounds, which effectively perform this role. Currently sulfur production is sharply marked from the number of other extractive industries that from the ecological point of view the most important problem is not achievement of sustained development condition by the sulfur production, but solution of problems of safe storage or even disposal of extracted sulfur. As against other extractive industries, which main efforts are focused on the search of more effective methods of production of required component against its decreasing world reserves, leading companies in sulfur industries worried first of all by the search of new ways for safe management by extracted by them resource
Complex modification technology of bituminous insulating materials
© National Academy of Sciences of the Republic of Kazakhstan, 2017. Strategic trend of modern oil refining industry is concluded in further extension of oil refining. On this evidence, development of intensive technology for processing of heavy oil residuals taking into account new scientific achievements on physical-chemical mechanics of oil dispersed systems [1], with a view to produce special bitumen with tailor-made properties and paint materials on their basis is actual task. High insulating properties with respect to aqueous media, as well as cheapness and practically inexhaustible domestic raw material base refer to the primary advantages of bitumen as a film-forming basis of paint materials [1-4] . Factors constraining wide use of coatings on the bitumen basis are their low physical-mechanical properties, i.e. hardness, adhesion and strength [5-9]. This is connected with raw material chemical composition features, technological conditions of the heavy oil residuals’ oxidation process [10] . It is expedient to use fluxes of heavy oils of naphtheno-aromatic base with minimal content of paraffin hydrocarbons, which reserves are extremely insignificant, as the raw material for production of special bitumen. In this connection, enhancement of the bitumen production raw material base by involvement of the heavy oil residuals of resin-paraffin base proves actuality of the topic

Some Aspects of Mathematical Modeling of the Geometric Structure of Porous Vermiculite Adsorbents Used in the Refining of Vegetable Oils
Currently there are high requirements for the quality of vegetable oils and fats, which is ensured only by a highly efficient technological cleaning process. Adsorption refining has become widespread, since the resulting products not only satisfy consumer demand, but also allow the removal of oxidation products, free radicals and other carcinogenic impurities from the oil. For such oil purification, it is necessary to select not only optimal oil refining modes, but also using effective adsorbents and bleach lands.
This article describes some aspects of mathematical modeling of the geometric structure of porous adsorbents, since one of the main tasks of porous adsorbents production is creation of high porosity, which is also characterized by the uniformity of the pore distribution over the volume of the layer. Ensuring optimal modes of porization processes and achieving the necessary geometric characteristics of the adsorption layer requires an understanding of the features of the layer structure formation and a theoretical description of this complex process, as well as the results of studies on the purification of cottonseed oil with expanded vermiculite from the Kulantau deposit and the characteristics of a new adsorbent for vegetable oils are presented.
Practical application development of theoretical aspects of the vermiculite adsorbent porosity effect on the quality of refined vegetable oil.
Key words: vegetable oil, adsorbent, Kulantau, vermiculite, porosity, geometric structure, refining
