The results reported indicate that the low molecular weight olefins (ethylene, propylene and butadiene) which are major gaseous hydrocarbon products of flash pyrolysis of coal derive from the same precursors in coal, whereas methane, benzene and other pyrolysis products are mainly formed from differ
