Summary An attempt was made to obtain mineral-carbon sorbents from waste products of petrochemical industry: lime from the decarbonization of river water to be used in technology and hydrocarbon wastes obtained in the treatment of industrial waste waters. The sorbents were prepared by thermal decomposition of mixtures of the mineral and carbon components. In order to optimize the preparation conditions, physicochemical studies were performed of both the mineral matrix and the mineral-carbon sorbents. Adsorption measurements involving nitrogen, water, and benzene as adsorbates were used for determining the parameters of porous structure of the obtained materials and their hydrophilic-hydrophobic properties. The properties influencing the sorptive properties of the organic compounds present in the petrochemical wastes were pointed out.

Mineral–carbonsorbents are produced by mechanical mixing of mineral and carbon substances or the deposition of carbon substance in the structure of mineral by inserting carbon precursors between gel particles and then its carbonization
In the present work an attempt was made to obtain mineral–carbon sorbents by thermal decompositon. The mineral matrix for
the sorbents (aluminium hydroxide) was based on petrochemical waste stream containing considerable amounts of aluminium chloride.
Reference tests were carried out with a model solution prepared with the use of analytical grade AlCl3. Atactic polypropylene and hydrocarbon mixtures obtained in the flotation of petrochemical waste waters were used as carbon-containing
The aim of this work was to determine the adsorption and structural characteristics of the complex sorbents and to check the
possibility of evaluation of their hydrophobic-hydrophilic properties.

In the present work an attempt was made to obtain mineral-carbon sorbents by thermal decomposition of solid waste materials
containing, besides to mineral components, solid petroleum derivatives. The amount and the homogeneity of distribution of
coal product formed in decomposition of organic matter on the surface of the mineral matrix, as well as the porous structure
of the sorbents obtained depend largely on the conditions of calcination of the wastes used. The aim of this work was to find
optimum conditions of the process. The sorptive properties of the obtained material were checked in the process of reduction
of pollutants contained in industrial wastes.
The present work is an attempt to use the waste water stream, containing considerable amounts of aluminium chloride, for the
manufacture of mineral–carbon sorbents. The use of the wastewater has given a possibility of obtaining a suitable mineral
matrix of aluminium hydroxide for the sorbents. Atactic poly(propylene) (APP) have been used as the necessary carbon raw material.
The modification of aluminium hydroxide was attained by preliminary mixing with the organic component, followed by carbonisation.
Optimum conditions for obtaining Al(OH)3 have been determined and the effect of the amount of carbon matter on the properties of the materials obtained has been evaluated.
The studies have enabled to trace the changes in the structure and properties of the sorbents obtained.
The purpose of this study was a preliminary evaluation of mineral-carbon sorbents preparation possibility by the method of
thermal decomposition of a mixture of aluminium oxide or hydroxide and acenaphthene and determination of their physicochemical
properties. The conditions of carbonization were established and the changes of physicochemical properties of obtained materials
as a function of organic substance content in the mineral-carbon mixture before the process of carbonization were tracked.
In these investigations the methods of thermal analysis, low-temperature nitrogen adsorption and benzene vapors adsorption
