Abstract
Modifying the low-calorific lignite from the Sergeevo deposit by means of liquid-phase catalytic alkylation with isopropyl alcohol was performed. The basic processes involved in the interaction of the coal under investigation with isopropyl alcohol were described. A positive effect of the alkylation treatment exerted on the coal bituminosity, the componential composition and the physicochemical characteristics of modified products obtained has been revealed.
