The invention relates to a reactor comprising a moving bed of solid particles that move in the direction of gravitation, and to a method for heating a reactor that comprises a moving bed, for the purpose of pyrolysis reactions.
Claims14
A reactor for carrying out a pyrolysis reaction, the reactor comprising:
- a high end and a low end;
- a reaction zone having a length and varying flow cross-sections over the length;
- a moving bed of solid particles having an outlet at the low end of the reactor and configured to move in a high end to low end downward direction;
- electrical electrodes disposed in an annularly concentric configuration within the reaction zone;
- and
- an educt inlet for gaseous educts and a product outlet for products, wherein the educt inlet and the product outlet are disposed in a manner so that in operation, an educt and product stream can move in a low end to high end upward direction in counterflow relative to a movement of the moving bed in the high end to low end downward direction.
