Process and device for reacting organic materials to give hydrogen gas

Abstract

Device (100) for reacting an organic starting material (1) to give a gas which comprises hydrogen, with: a feed device (30), a tubular furnace (20) with an entry zone (E), an interior space (I), an axis (R) of rotation and an exit side (A), a water feed (31) arranged in the region of the feed device (30) or entry zone (E), in order to permit addition of water (W) to the starting material (1), where the arrangement and design of the feed device (30) and the tubular furnace (20) are such that via the feed device (30) it is possible to feed the starting material (1) in the region of the entry zone (E) into the interior space (I) of the tubular furnace (20), and a solid material (2) and a gas mixture (3) can be discharged at the exit side (A) of the tubular furnace (20), where the tubular furnace (20) comprises a first zone (Z1) and a second zone (Z2), the first zone (Z1) being in a region between the entry zone (E) and the second zone (Z2), and the second zone (Z2) being in a region between the first zone (Z1)and the exit side (A), the tubular furnace (20) comprises a compensator (21) designed for compensation of different thermal expansions of the first zone (Z1) and the second zone (Z2), arranged at the exit side (A) of the tubular furnace (20) there is a gas-conducting system (40) designed to conduct the gas mixture (3) onward, arranged in the region of the gas-conducting system (40) there is a gas monitor (41), the gas monitor (41) being designed to monitor the content of hydrogen in the gas mixture (3), the water feed (31) being amenable to regulation as a function of the content of hydrogen in the gas mixture (3).

Description

technical field [0001] The invention relates to a high-temperature furnace heated by means of a heating device and to a method of using such a furnace in order to convert organic material into synthesis gas. In particular, they relate to tubular furnaces which are suitable for processing carbon- or hydrocarbon-containing raw materials, such as waste (garbage), waste (food waste), biological material (Biomasse) and the like. Background technique [0002] There are various furnaces that are heated, for example, using induction coils. An example is known from International Patent Application Publication No. WO09010086A1. Another example is known from European patent EP 1495276 B1. [0003] It has been found that problems arise with the reliability of such induction furnaces when very high temperatures occur over prolonged periods of time or when very aggressive materials are released into the furnace. Oxygen emerging from the material to be converted can, for example, corrod...
