THE USE OF CARBON CONTAINING SOLID RESIDUE OF PYROLYSIS OF RETIRED CEREALS-AGABARITIC TIRES
By far the most environmentally safe method of disposal of used tires with production of a valuable chemical raw material is pyrolysis. In Kuzbass by pyrolysis of rubber utilized on the company "Connectology plus" (Kaltan) using the unit pirotex. In the pyrolysis process are formed orogeny solid residue pyrolysis oil and the pyrolysis, the application of which is submitted.
The most interesting of products of pyrolysis of tires today is the solid carbon residue (UTO). In the literature there are recommendations on the possibility of using UTO as a pigment (e.g. paint industry), filler for polymers, as well as for the production of sorbents. However, the use of UTO in a particular area it is necessary to know certain physical and chemical properties. For example, in table. 1 presents the main physico-chemical properties of the UTO necessary for the production of adsorbents, pigments and fillers for polymers.
Table 1
Main physico-chemical properties of the UTO, depending on the scope of
Scope Feature
The production of sorbents The structure of the particle (porosity), the composition of superficial functional groups, strength, purity, hydrophilic, bulk density, adsorption capacity, pH.
The production of pigments (e.g. paint industry) Dispersity, hiding power, coloring power, resistance, oil absorption, light fastness, alkali, acid - and voloshinojj.
Production of fillers for polymers The true and bulk density, dispers-ness, moisture content, and volatile, the rash occurs-honor, pH, hardness, specific surface
However, the RTI processors provide insufficient information about the physico-chemical properties of the UTO. One of the significant factors is the variety of raw materials (MRG made the basis of chloroprene rubber (Nairit), nitrile butadiene rubbers, etc.) and process parameters of pyrolysis (temperature and time).
The aim of this work was to study the physico-chemical properties of the UTO received on the company "Connectology plus". The raw material used disused heavy tires (CGS). The main raw components are KGS natural and synthetic rubber (styrene-butadiene rubber, isoprene etc.) where the content of natural rubber can reach 90 %, which has a significant influence on the properties of the UTO.
Physico-chemical properties of the UTO was determined by standard methods, the results of the study are presented in table 2.
Table 2
Physico-chemical properties of the UTO pyrolysis KGS
Physico-chemical properties The value
pH of water suspension 5-7
Analysis moisture (W), % 0,4±0,03
Ash content, % 0,3±0,1
Bulk density, kg/m3 318±0,2
Dispersion microns, not more than 10-40
Absorption of dibutyl phthalate, cm3/100 65±6
Mass fraction of sulfur, % 2,4±0,2
Oil absorption, g 114,5
Thus, in table properties do not differ from the properties of carbon black grades n701, n705, n803 produced from traditional raw materials (gas, coal, oil) according to the known technology (furnace, etc). Therefore, the UTO obtained by pyrolysis on the company "Connectology plus", can be used as a pigment in paint industries [1].

THE USE OF CARBON CONTAINING SOLID RESIDUE OF PYROLYSIS
OF DISUSED TIRES
To date the greatest interest from the products of pyrolysis of rubber products is carbon black (soot). In the literature there are recommendations on the possibility of using this carbon residue (UTO) as a pigment in the paint industry, filler in Rezina industry and for the production of sorbents. But in order to use UTO or where it is necessary to know its specific properties. However, the RTI processors provide insufficient characterization of the physico-chemical properties of the UTO. [1].
The aim of this work was to study the physico-chemical properties of the UTO received on installation goes out on the company "Connectology plus" (Kaltan). The raw material used disused heavy tires (CGS), which contains 90% natural rubber, which has a significant influence on the properties of the resulting UTO. The results of the experiment are presented in the table:
