Abstract
Coke gas is a valuable fuel for metallurgical plants and a promising energy technology raw material, particularly for hydrogen energy. Absorption oil is used for gas purification, its prevention from thickening is an important task, so it is necessary to clarify the factors and mechanism of oil density increase in the process of its operation. For this purpose, the similarity and difference of products of oil polymerization in factory conditions with artificial polymerization of a separate fraction were established. Petrographic studies have shown that oil deposits in industrial equipment are represented by polymer-like material (94 %) with inclusions of coal particles (4 %). The results of infrared (IR) spectroscopy indicate certain similarities in the structure of substances and the presence of functional groups, which gives reason to believe that oligomerization products of absorbing oil components are present in the polymers of the benzene compartment, in the solid sediments and in the artificially obtained indene coumarone resin. It is shown that ammonia promotes the separation of ferrocyanide precipitates from the absorbing oil.
