ANALYSIS OF COAL-TARRESIN FRACTION OF SHUBARKOL LOCATION

Abstract

In this article one of main type of raw material used for the production of sulfur-free petroleum and tetralin is considered. The physico-chemical characteristics of the coke-chemical resin produced by coal devolatilization of the Shubarkol raw and the tar fraction with boiling point up to 180, from180 up 230 and from 230 to 280°C have been examined. Three fractions of initial resin had been analyzed applying gas chromatography-mass spectrometry with boiling point up to 180, 180-230 and 230-280°C. It was pointed that the chemical composition of distillate fractions of resin consists of alkyl derivatives aromatic hydrocarbons with the number of aromatic rings of 1-4. Benzene and its methyl-, ethyl- and propyl- derivatives were identified with the boiling point up to 180°C.The composition of the fraction with boiling point up to180-230°C consists mainly of trimethyl- and ethyl derivatives of benzene, phenol and its methyl derivatives. The composition of distillates with boiling temperature up to 230-280° C includes individual aromatic compounds and their derivatives with a higher molecular weight.
