ABSTRACT:
An apparatus for making the supply of a material liquid and relief of pressure of a reaction product liquid in a high-pressure liquefaction reaction such as direct liquefaction of coal. The apparatus includes at least one cylinder having two working chambers separated by a movable float, one of which is adapted to receive the material liquid while the other is adapted to be charged with high-pressure product liquid. A gas discharging pipe having a valve is connected to the side of the cylinder to which the high-pressure product slurry is to be charged. For delivering the product slurry from the cylinder to the outside of the system, the pressure in the cylinder is beforehand relieved and the gases separated from the product slurry are discharged through the valve of the gas discharging pipe. Thereafter, the product slurry filling the cylinder is delivered to the outside by a low pressure of the material slurry supplied to the other side of the cylinder.
