Studies on the thermal decomposition of coal macerals. Part-II

摘要

Vitrinite, exinite and fusinite from a high sulphur Indian coal have been pyrolysed in the range 300-800 deg at an interval of 100 deg. The comparison of the gases evolved in each case with those obtained from a phenol-formaldehyde resin derivative under similar conditions, reveals that alkyl and/or aryl ethers play an important part in the structure of exinite whereas methylene and ethereal linkages are important constituents of vitrinite while fusinite possesses a highly condensed structure.
