ABSTRACT:
Particulate solids are fed into a pressure reactor operated under a pressure of 5-150 bars by means of a guide cylinder which is secured to the reactor and surrounds the reactor inlet. The guide cylinder is adapted to be closed and a stationary feed conduit is directed towards the guide cylinder. A cylinder container, which is gastightly guided in the guide cylinder and has a bottom which is adapted to be closed, is moved up and down in the guide cylinder and when the bottom of the cylinder is open and the reactor inlet is closed the material flows out of the container into the guide cylinder whereas the bottom of the container is closed and the same is moved toward the open reactor inlet to displace gases into the reactor. The device for carrying out the process includes a guide cylinder secured to the reactor and surrounding the reactor inlet. The guide cylinder is adapted to be closed. A stationary feed conduit is directed towards the guide cylinder and a container is gastightly guided in the guide cylinder and is movable up and down therein and has a bottom that is adapted to be closed.
