ABSTRACT:
The residues obtained in the hydrogenation of oil, especially heavy oil, or of coal are subjected to low temperature carbonization in a drum, preferably a rotary drum, at temperatures between approximately 400.degree. C. and approximately 600.degree. C., by means of a carbonization gas after the separation of the condensable portions and heating to temperatures between approximately 600.degree. C. and approximately 950.degree. C. which is introduced into the low temperature carbonization drum. The gas is heated to temperatures between approximately 600.degree. C. and approximately 950.degree. C. indirectly by flue gases arising from the combustion of oil or gas, for example, of excess carbonization gas. The residue to be carbonized at low temperature is introduced into the hot gas in a finely dispersed state and preferably atomized.
