Pyrolitic gas chromatography proved to be a tool for defining the type of polymer and studying the composition of gaseous and liquid pyrolysis components. In this paper pyrolitic gas chromatography was used to detect the composition of wastes of two synthetic rubber productions. Further, the authors study the kinetics of decomposition of these types of wastes in the range of temperatures of 500–700 °C. In the process of pyrolysis the main products for the first sample were divinyl, isoprene and dipentene, for the second sample—divinyl, isometric vinylcyclohexenes and styrenes. The kinetic parameters of the pyrolysis of wastes of synthetic rubbers were determined using pyrolitic gas chromatography. The activation energy was in the range of 239 kJ/mol for wastes of diene rubber production and 352 kJ/mol for butadiene-styrene rubbers production wastes. The data obtained will allow simulating the processing plant for these types of waste, as well as allow you to select the necessary conditions to increase the yield of target products. |
