Abstract

Hydrocarbon energy resources are the basis of the economy of Kazakhstan, among which oil, coal, and gas stand out. Kazakhstan is among the top 10 countries in terms of proven coal reserves of 29.4 billion tons (about 2.4% of world reserves), where 2/3 is brown coal, 1/3 is hard coal [1]. The issue of deep processing of low-grade hydrocarbon raw materials (fine coal, high-ash coal) and “unconventional hydrocarbon raw materials” (high-viscosity oils, natural bitumens, resins, etc.) remains especially relevant for the coal industry of Kazakhstan. This article conducts a study of joint low-temperature pyrolysis of high-ash coal from the Borly deposit with natural bitumen (at different ratios of coal and coal tar with bitumen) on a Fischer retort. The main product of pyrolysis is semi-coke, and tar and flammable gas are also present in smaller concentrations. The results of elemental analysis and calorific value of samples of the initial raw materials and their pyrolysis products are presented, as well as the results of an analysis of the physicochemical parameters of the resin obtained from the studied samples.
