✦ Synopsis

Heating the same weakly-caking coal as was used in previous work in thin layers in nitrogen resulted in an evolution of hydrocarbons in two distinct stages. Only small amounts were obtained up to 250°C, the boiling ranges of which corresponded to those within which the coal was heated for their liberation.

Above 250°C, the boiling ranges were wide; a tendency was discernible; though not as clearly as in solvent extraction, for molecules to emerge in an order of diminishing molecular size. The manner of retention of the hydrocarbons in the coal is thought to explain this.
