ABSTRACT A process for hydrogenation of carbonaceous materials such as coal, heavy oil, bitumen, and the like comprising a) contacting said carbonaceous materials with hydrogen and a hydrogenation catalyst at a temperature of 250°C to 550°C and a pressure of 50 to 700 bar, whereby gaseous products, liquid products and a solid sludge are formed, b) separating said sludge from said products at a temperature up to 100 K lower than the hydrogenation temperature of step a), c) stripping said sludge of any liquid products contained therein by contacting said sludge with a process gas comprising at least a portion of said gaseous products at a temperature of 20°C to 300°C and a pressure of 10 to 300 bar, whereby a process gas stream containing said liquid product is formed, and d) separating said liquid products from said process gas stream.
