The Study of Liquid Phase Adsorption on Nanostructured Sorbents in Oil Disperse Systems

Kinetic characteristics of sorbents synthesized from gypsum were studied in a wide range of particle sizes from 15 nm to 1.5 mm. The resulting sorbents based on calcium silicates are chemically and physically stable up to temperatures of 900 - 1,000 K, and represent a suitable material to produce carriers for a wide range of substances. Plate sorbents with a thickness of 1.5 mm were formed from them by sintering. Kinetics of adsorption of each part of oil disperse system was studied. By using the method of immersing the plates in a model oil disperse system, dispersed phase was selectively adsorbed on each plate. The residue of non-adsorbed part of oil disperse system in the experiments did not exceed 2% by mass. The results are useful for modeling oil disperse system in general and in practice for improvement of technological processes of obtaining target products from oil, as well as in the development of disposal and recycling technologies for wastes of production of target products from oil disperse systems.
