The problem of rational use of brown coal from the Kangalassky deposit is associated, first of all, with a high content of fine fractions, reaching up to 50 % of the total amount extracted. The rational methods of efficient use and conservation of coal, in the first place, include the briquetting of fines, which uses the task of converting a low-grade, having limited sales of fuel, into a full lump fuel, convenient for transportation, long-term storage and incineration.<\/p>\n<p style=\"text-align: justify;\">The authors selected binder from the oil of the Talakanskoye field, modified to improve the adhesion interaction, mechanically activated organic and mineral fillers: dried lake sapropel, natural zeolite, and brown coal. A prerequisite for the use of dispersed substances of organic and mineral origin as modifying additives in the filling of binder in the technology of briquetting brown coal, in addition to an extensive resource base and cheapness, were their specific properties due to their increased specific surface area, porosity, and high adsorption characteristics.<\/p>\n<p style=\"text-align: justify;\">The optimal compositions and technological regimes for obtaining composite coal fuel briquettes have been determined, and the technical characteristics of the briquettes obtained have been determined.<\/p>\n<p style=\"text-align: justify;\"><strong>Keywords:<\/strong> briquette; brown coal; binders; tar; sapropel; zeolite; briquetting<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Nikolaeva Lira Aleksandrovna Russian academy of sciences Institute of oil and gas problems of the Siberian branch, Russia, Yakutsk E-mail: lanikolaeva_ipng@mail.ru Abstract.
