Abstract: The article presents the results of a study of the process of low-temperature pyrolysis in a stream of inert gas. To study this process, an installation was developed with automatic continuous online control of the composition of the gas and liquid phases. The study of the qualitative and quantitative composition of gaseous and liquid products of thermal destruction at a temperature of 700 ° C was carried out. The composition of the gaseous products was determined using a SRS QMS 300 quadrupole gas mass spectrometer. The gaseous products were a mixture of C1-C6 hydrocarbons, hydrogen, carbon oxide and dioxide, hydrogen sulfide and ammonia. The work describes in detail the method of work on the installation, including the method of conducting experiments and analyzing the obtained products of thermal destruction of coals.

Key words: pyrolysis coal liquid products gaseous products chromatography mass spectrometry
