Abstract
Methods and apparatuses for producing fuel and power from the reformation of organic waste include the use of steam to produce syngas in a Fischer-Tropsch reaction, followed by conversion of that syngas product to hydrogen. Some embodiments include the use of a heated auger both to heat the organic waste and further to cool the syngas.
Claims15
A method for calcination of organic material, comprising:
- providing a kiln having two opposing ends with a waste entrance and a syngas exit at one end and a non-rotating reactor containing a steam reformer comprising heating elements at the other end, and a rotatable outer wall including a helical spiral flight affixed to an interior of the rotatable outer wall;
- conveying organic material from the entrance toward the other end by rotation of the spiral flight;
- heating the organic material by the steam reformer to form hot syngas;
- directing the hot syngas into the reactor and around the heating elements;
- heating the spiral flight by flowing the hot syngas from the reactor toward the syngas exit;
- and
- reheating the syngas with waste heat from the kiln;
- wherein the spiral flight and a portion of the rotatable outer wall combine to create an internal gas passage, and said heating the spiral flight is by flowing the hot syngas within the internal gas passage.
