Title:
CARBON-BASED FUEL PRODUCTION METHOD AND CARBON-BASED FUEL PRODUCTION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/091492
Kind Code:
A1
Abstract:
A carbon-based fuel is produced from an organic material using an extruder. A carbon-based fuel is produced through: a first step for providing an extruder provided with a cylinder 110, screws S1a and S1b that are arranged rotatably in the cylinder 110 and a rotary drive mechanism 150 for rotating the screws; and a second step for supplying an organic waste material OW and a plastic PL from a hopper 130 arranged at an upstream part of the cylinder and kneading a melted product of the organic waste material OW and the plastic PL to carbonize the kneaded product. In the second step, a dry-distilled gas generated as the result of the carbonization is removed using a vacuum pump connected to a cylinder 210 that is connected to the cylinder 110 while pushing the kneaded product through the cylinder 210 using a side vent stuffer. According to this production method, a carbon-based fuel can be produced from an organic waste material with high efficiency while preventing the occurrence of entrainment.
