Patent ID: 8354006

Claim:
A device for pyrolysis of a material, comprising a receiving chamber for receiving the material and extending horizontally in a first direction; compressing means compressing the material received in said receiving chamber so as to form a compact body and including a cylinder-piston unit with a compressing plate on a piston rod movable horizontally in said first direction; a pyrolysis chamber for subjecting the compact body to a heat treatment to generate a pyrolysis gas and extending horizontally in said first direction so that said compressing plate of said cylinder-piston unit, after moving in said receiving chamber, moves further horizontally in said first direction to enter said pyrolysis chamber and to continue moving horizontally in said first direction in said pyrolysis chamber; separating means as a partition separating said receiving chamber from said pyrolysis chamber and moveable in a second direction which is perpendicular to said first direction between a closed position in which said partition of said separating means separate said receiving chamber from said pyrolysis chamber for compressing the material received in said receiving chamber by said compressing plate and an open position in which said partition of said separating means is withdrawn and open a communication of said receiving chamber with said pyrolysis chamber horizontally in said first direction so that the compact body can move horizontally in said first direction from the former into the latter by said plate of said cylinder piston unit, said receiving chamber and said pyrolysis chamber being aligned with each other and forming a continuation of each other horizontally in said first direction with substantially identical inner cross sections, so that when the compact body transits from said receiving chamber into said pyrolysis chamber horizontally in said first direction after said partition of said separating means is withdrawn in said second direction perpendicularly to said first direction it said compact body is in tight connect contact with inner surfaces of both said chambers, which tight contact prevents a flow of a gas pyrolysis gas from said pyrolysis chamber back into said receiving chamber and a flow of air from said receiving chamber into said pyrolysis chamber.
