Nitrogenous Substances and Means of Studying the Molecular Structure of Fuels

摘要

Solid fuels, such as coal, are composed of high-molecular compounds. The genesis of the petrographic elements of coal is discussed. Studies of the nitrogeneous compounds are sorely needed. Products of thermolysis of fuels contain virtually no primary and secondary amines; all of the nitrogeneous compounds of the tars are pyridine bases. A scheme for the formation of these pyridine bases and of heterocyclic compounds is proposed. The chemical composition of coal macerals and the structure of fractionated compounds in these macerals are considered. The composition of the humus is also discussed. (ERA citation 06:016401)
