Abstract
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.
