Preparation and texture of mineral-carbonaceous sorbents

100%

Grzybek T. , Krzyżanowski A. , Motak M. , Żyła M.

tom Vol. 72, nr 7

1242-1248

Some physico-chemical properties of mineral-carbonaceous sorbents were presented. They were obtained by pyrolysis of either sodium montmorillonite or pillared montmorillonite filled with synthetic polymer. This procedure resulted in the introduction of carbonaceous deposit into the porous structure of the mineral. In the case of the sodium form, nonporous products of carbonization resulted in the increase of basal spacing d-001 but in the same time they blocked the interlayer spaces.The initial of montmorillonite obtained by intercalation with aluminium hydroxycations led to the formation of a stable microporous system. Sorption of polymer and its carbonization resulted in a formation of carbonaceous deposit on the surface of the mineral with the preservation of relatively high specific surface area and porosity.
