Abstract
An apparatus for effectively making the supply of material slurry at a high pressure into a high-pressure liquefaction reaction vessel and relief of the pressure of the high-pressure product slurry to permit the discharge of the product slurry as a low-pressure slurry. At least one cylinder having a float therein is used. The material slurry is charged at a low pressure into the cylinder from one end of the latter. Then, the high-pressure product slurry after the reaction is charged from the other end of this cylinder or another cylinder so that the material slurry is pressurized and forcibly supplied to the reaction vessel by the high pressure possessed by the high-pressure product slurry. On the other hand, the high-pressure product slurry, which has been relieved from the high pressure, is forced out of the system at a low pressure as a next batch of material slurry is charged into the cylinder from the above-mentioned one end of the cylinder, so that the product slurry is collected as a low-pressure slurry.
