Abstract
Treatment with highly dispersed adsorbents is a necessary stage of purification of vegetable oils, natural and hydrogenated fats, as well as fatty acids from coloring substances, trace amounts of phospholipids, sulfur compounds, fatty acid salts with alkaline and other metals, some oxidation products, etc. Adsorption capacity of the adsorbent is dependent on the concentration of the substance in the liquid or vapor phase, its partial pressure, temperature, and the initial state of the adsorbent.At the swelling a cellular porous structure is formed, total porosity that connects with the entered number and the content of the gaseous component masses.The rheological characteristics of porous masses have the decisive effect on the porous structure.The research results of the internal structure of adsorption layers by the adsorption isotherms means indicative of the internal surface of the porous layer is characterized by an extremely complex and developed form and can be described by means of fractal geometry.A model of the geometric structure of mica materials formed in the process of blistering during heat treatment is developed.The presented model has sufficiently general form and can be used both in the organization of systematic experimental studies of porization and adsorption in the adsorption layers of highly porous, and for the porization vermiculite optimization.
