Abstract
Hydrocracking of destructive chemical disintegration extracts under hydrogen pressure of Hokkaido coals has been studied at the reaction temperature of 425°C, the hydrogen pressure of about 200kg/cm2, and the reaction time of 1 hr., using 1l rotary type autoclave and a massive quantity of zinc chloride catalyst.
Hokkaido coals' extracts could be easily and effectively hydrocracked into low boiling distillable fraction at the above reaction condition.
By the differance of extracts obtained from differant coals and at the differant extraction temperatures notable feature or relation could not be found in gaseous and liquid products.
But it was very feature that in-230°C fraction aromatics were contained in a great quantity and olefines were negligible and that in gaseous product iso-butane was in a large quantity comparable with n-butane.
Further, the components in-150°C fraction and aromatics in 150-230°C fraction were analysed gas-chromatographycally.
