Abstract
Applying heat from a heat source to a first region to cause a first pyrolysis process, the first pyrolysis process resulting in a gaseous mixture, and applying heat from the heat source to a second region to cause a second pyrolysis process, the second pyrolysis process being applied to the gaseous mixture, wherein the second region is located closer to the heat source than the first region. Pyrolysis is used to destroy oils, tars and/or PAHs in carbonaceous material.
Claims8
An advanced thermal treatment (ATT) apparatus comprising:
- a first advanced thermal treatment (ATT) region, wherein the first ATT region comprises a cylindrical retort;
- a second ATT region, wherein the second ATT region comprises a gas enclosure;
- a third ATT region located in between the first region and the second region, wherein the third ATT region is a system of piping;
- and
- a heat source being positioned such that, when operated
- the heat source heats the first region to cause a first ATT process, the first ATT process resulting in a gaseous mixture, and
- the heat source heats the second region to cause a second ATT process, the second ATT process being applied to the gaseous mixture, and
- the heat source is further adapted to heat the third region to cause a third ATT process, the third ATT process being applied to the gaseous mixture;
- and
- wherein the second ATT region is located closer to the heat source than the first region.
