Recovery of Raw Materials by Pyrolysis

摘要

With the conventional pyrolysis technologies it was formerly possible to treat one specific waste only. A new technology which enables to process a great number of hydrocarbonaceous industrial wastes, even in mixture was developed. The technology was developed in both, a laboratory and in a testing plant with a capacity of 200 kg/h and within 3000 operating hours successfully proved. Residues from car shredding plants, plastics, used cables and acid tars were pyrolysed separately as well as in a mixture. The pyrolysis products thus gained are upgraded in a succeeding stage to meet market demands or for use in a secondary refinery. The calculation of profitability for a large plant proves that a balanced operating result can be reached. In industrial areas this technology will play an important part with regard to waste disposal as well as resource recovery.
