<p>The disclosure pertains to a process for the low-temperature catalytic conversion of organic waste and to apparatus for carrying out the process. Shredded waste is heated within the confines of a conversion line while air is excluded and the gas stream drawn off from the conversion line at various temperature stages and containing the conversion gases thus produced is cooled to condense the conversion gases produced at different temperatures before being led in the circulation back into the conversion line. In order to create favourable conversion conditions, it is proposed that: the waste should be conveyed in a circulation system through the conversion line which should be heated at set time intervals from one temperature level to the next level; the waste carried by a nitrogen conveyer gas stream along the conversion line should be discharged from the circulating conveyer gas stream downstream of the conversion line and fed back into the conveyer gas stream upstream of the conversion line, at least a portion of the conveyer gas stream being cooled for the purpose of condensing the conversion gases; and the time interval between different temperature stages should be adjusted in accordance with the build-up rate of at least one conversion gas, preferably carbon dioxide, within the confines of the conversion line.</p> |
