ABSTRACT OF THE DISCLOSURE A process for liquefying and gasifying coal by thermal treatment in the presence of hydro ? gas for hydrocracking is disclosed. The process comprises a sequence of the following two steps: (1) coal fines are injected into a heated hydro ? s stream at a pressure of from 35 to 250 kg/cm G such that they are rapidly heated to a temperature of from 750 to 1100°C for thermal cracking thereof; and (2) the resulting product is subjected to hydrocracking for a period of from 1.0 to 60 seconds at a temperature that is lower than the temperature us ? in the first step and which is in the range of from 570 to 850°C.
