Abstract: A pyrolysis system includes a source of feed material having carbon and unit rests upon a support surface and has a feed material inlet coupled by the feed material transport system to the source of feed material. The pyrolysis unit defines therein a reaction chamber having a length and having the feed material inlet defined at one end thereof. The reaction chamber defines a material flow axis in the reaction chamber from the feed material inlet along its length that is oriented one of parallel to and at an acute angle relative to the support surface. The pyrolysis unit defines at least one outlet for extraction of at the least one of a solid, gaseous and liquid fuel from the reaction chamber.
