<p>The invention relates to a method and a device for preparing products containing hydrocarbons by pyrolysis, especially for preparing old tires and/or comparable rubber products, and plastics and the like. According to the method: once the reactor (2) has been loaded, it is inserted into a thermal furnace (1); the reactor (2) is heated, during a first stage, to a temperature of between 80 and 120° C., which is maintained over a period of approximately 20 minutes, and nitrogen is blown into the reactor (2) during a second stage running in parallel; the humidity and oxygen contents are reduced in the reactor (2); the temperature is increased again in the reactor (2), during the subsequent process stages, to between 360 and 420° C. over a period of between 1 and 2 hours; the process temperature is briefly increased during the subsequent stage, to 480° C. and up to a maximum of 600° C., for a period of between 10 and 60 minutes; following pyrolysis, the pyrolysis gas is drawn off the reactor (2) and supplied to a cooling and relaxing module (4), while the carbon deposited in the bottom of the reactor (2) is sucked up and the metallic components are removed from the reactor (2). The inventive method is carried out by means of a device consisting of at least one reactor (2) that can be inserted into the thermal furnace (1). According to the invention, the bottom (18) of a reactor (2) has a concave shape, the cover (17) is embodied with a guiding projection (28) which engages with a cover receiving element (22) in the closed state, and reflectors (30) and edge reflectors (31) are formed on the inner side of the cover (17).</p> |
