✦ Synopsis

In order to make clear the effect of pressure upon the gaseous products on pyrolysis of coal, experiments were carried out using a flow-type apparatus under helium pressure up to 9OO"C, changing both the superficial velocity of carrier gas and the height of the coal bed. No significant pressure effects on the gaseous products were observed.

An increase of methane evolution was found above 600Β°C on account of the decrease in superficial velocity and the increase in height of the coal bed.

The carbonization of an industrial coal-tar pitch was studied by using a tube bomb, as a function of carbonization temperature (SSOY-SSOOC) and inert gas pressure (l-20 bar), and resultant green cokes were evaluated according to electrical resistivity determined using the Van der Pauw method. At 55O
