Abstract

The present invention relates to a novel method for pyrogasification of organic waste. The inventive method uses a vertical furnace (1) filled with metal masses in the form of metal toroids (2), previously heated to a high temperature (500 to 1100 DEG C), and organic matter (3) to be pyrolysed. The method also involves a furnace (9) suitable for heating the toroids (2) conveyed by an Archimedes screw (18) driven by a gear motor (19), as well as a separator (11) for recovering the mineral residue (12), the toroids (2) and the residue (12) being separated using a screen (14) and an Archimedes screw (15) driven by a gear motor (16). The inventive method can be used for treating all products which contain organic matter, whether from biomass and thus considered renewable energy, or not from biomass.

Description

technical field

[0001] The invention relates to a new method for cracking and gasifying organic waste. Background technique

[0002] Pyrolysis gasification is a method of processing organic matter and recovering energy from it.

[0003] In this description, "organic matter" and "organic waste" are understood to mean the matter contained in waste and agricultural and biomass products and by-products.

[0004] Energy recovery from waste and biomass is of the greatest interest today due to its commitment to effectively combat the greenhouse effect and future shortage of fossil fuels.

[0005] The method according to the invention utilizes the pyrolysis gasification of organic matter.

[0006] Several pathways exist for energy recovery from organic matter:

[0007] - incineration, a well-known and widely used method, is currently criticized due to its installation costs and especially its high off-gas (dioxins, furans, heavy metals, etc.) remediation costs;

[0008] - Methan...
