bentonite clay

The problem of accumulation of spent sorbents is considered in the article; The main methods of desorption of pollutants and regeneration of sorbents are described; the effectiveness of the method of chemical desorption for extracting Nikel ions (II) from bentonite clays is investigated; the main ways of utilization of spent sorbents are considered

The cooligomers production using С9 fraction of diesel fuel pyrolysis liquid products in the presence of silica-alumina acid type catalysts: activated palygorskite and activated bentonite clay has been investigated. Dependences between process conditions and cooligomer yield as well as between conditions and cooligomer properties have been studied. The relation between the catalysts properties and results obtained in their presence has been analyzed. The catalysts comparative analysis has been carried out.
