The aim of the study is to develop the preparation of microporous adsorbents (PC) based on montmorillonite and basic aluminium salts from concentrated dispersions, to study their adsorption and catalytic properties. In the studies, the adsorption, photometric, spectrometric, X-ray and chromatographic methods were used. The samples of PC were prepared with interlane distance 1,7-1,8 nm, specific area in the range 140-300 m2/g and pore sites 0,7-2,1 nm. The physico-chemical properties of the material prepared are not worse than those characteristic for the bast analogues worldwide. The material was shown to be promising for the cleaning of waste waters from phenol, anionic dyes, and as the catalyst for the alkylation of phenol by olephins. The laboratory technological regulations are developed for the preparation of the adsorption of the adsorbent hydroxy aluminium montmorillonite. The technolo gy is developed for the preparation of PC based on the disperse minerals from Ukrainian deposits. The synthesised material can be used as a new efficient catalyst in the petrochemical industry. Product Description popup.authors popup.nrat_date 2020-04-03 Close
