Abstract
Composition of coal from the new northern deposits of the Lena Basin and its reactivity in the processes of thermal dissolution and hydrogenation were investigated. It was established that the content of rare earth elements in the coal under investigation in some cases is 5-10 times higher than the industrially significant indices. The results of thermochemical transformation of coal into liquid substances are presented. Qualitative relations between the transformation degree during thermal dissolution and the data on the technical analysis of carbon - hydrogen concentration and the yield of volatiles - were determined. The suitability of the coal from the Lena Coal Basin for obtaining liquid fuel by means of the catalytic hydrogenation is substantiated. The reasonableness of complex processing of coal with the separation of rare earth concentrate is stated.
