Use of catalytic processes for gasification of organic materials
The paper presents the results of studies of catalytic gasification (pyrolysis) of peat and peat-mineral compounds. The increase in the heat of combustion of gas with increasing concentration of hydrocarbons has been experimentally proved. The use of aluminosilicate-mineral materials under or near peat deposits as catalytic systems has been substantiated.

Hardware and technological complex for deep processing of secondary resources (low-concentrated liquid wastes containing nonferrous metal ions)
- Authors:
- V. A. Kolesnikov
- V. I. Ilin
The object of research is galvanic production waste in the form of low-concentrated solutions containing nonferrous metal ions. The aim of the work is to develop a hardware and technological complex for deep processing of secondary resources using advanced technologies (membrane, electroflotation, electrochemical). Experimental studies of electroflotation extraction of Ni 2+ , Zn 2+ , Cu 2+ ions in a flowing electroflotation apparatus with an electro pH corrector were carried out. Optimal conditions of extraction were determined. The mathematical model of the process is created. Two main directions of use of flotation concentrates of individual hydroxides of copper, zinc, nickel, cadmium are proposed.

Universal electrochemical analyzer of quality and safety indicators of environmental objects for the purposes of ecological monitoring
A universal electrochemical analyzer for environmental monitoring has been developed. The analyzer is designed for efficient automated determination and control of quality and safety indicators of environmental objects of current regulatory standards, such as concentrations of toxic metals, organic toxins, impurities. The analyzer provides simultaneous performance of a number of electrochemical techniques for electroanalytical experiments. A new scheme of the universal measuring system has been developed, original algorithms of instrumental processing of electrochemical sensor signals have been proposed and applied. The application area of the electrochemical analyzer is the bodies of state and industrial environmental control and product certification.

Installation of automatic sorting-mixing of metal-containing wastes
A prototype of a magnetic pulse separator was developed. The technology of automatic extraction of non-ferrous metal from smelting contaminated scrap metal with simultaneous separation by density (sorting aluminum and its alloys from copper and copper-zinc alloys) has been developed. The proposed separation method for processing of industrial and household waste contaminated with non-ferrous metal (e.g., old refrigerators, washing machines, automobile and truck transport, household waste with the contents of beer cans, etc.) can be used.

Physico-chemical basis for the effective functioning of technological equipment in the gasification of solid fuels and organic waste
The results of studies of low-temperature gasification processes of different types of peat and organic sapropel are presented. Various catalytic systems based on platinum group metals have been used to increase the calorific value of combustible gas and simultaneously to decrease the gasification temperature. It is shown that an increase in the combustion heat of the resulting gas occurs due to an increase in the proportion of hydrocarbons in the gas mixture.
