โœฆ Synopsis


The characteristics of tars made in a short-path vacuum still (previously termed volatile solids') are compared with those of low-temperature tars previously made.

The compositions of the volatile products from Gray-King low-temperature carbonization assays of five coals are considered, with reference to our previous work showing the relations of the hydrocarbons and the oxygen-containing structures in coal to those in such products.

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 250ยฐC, the boiling ranges of which corresponded to those within which the coal was heated for their libe

Exhaustive, stepwise solvent extraction of an orthohydrous and a perhydrous (cannel) coal in an autoclave at a maximum temperature of 300ยฐC gave yields of aliphatic and aromatic hydrocarbons approximating to those found in the corresponding low temperature tars from these coals. Benzene was the main

The technique of steaming coal for long periods at temperatures up to 600ยฐC. collecting the total products made up to a particular temperature, and also, in a separate series of experiments, stepwise between temperatures within this range, has enabled a fuller study to be made of the sequence of eme
