METHOD FOR PRODUCING SYNGAS FROM CARBON BASED MATERIAL

摘要

“Syngas” is produced from carbon based material in a system comprising means for feeding material into the system, means for combustion thereof, means for use of Syngas and means for extraction of combustion residues, combustion means comprise: a sealed combustion chamber, with temperatures of 300-600° C.; device for injection of gas into the combustion chamber; device for monitoring the quantity of gas introduced/to be introduced into the combustion chamber, where the method comprises: introducing the material into a combustion chamber at a constant temperature of 300-600° C.; residence of the material therein for 5-13 hours; the residence time allowing a combustion to decompose organic molecules of the material producing Syngas, continuously drawn off, and carbonous residues; residence of the carbonous residues at the temperature for 7-13 hours with excess air; the excess air for completely incinerating the carbonous residue; and use of the Syngas and extraction of the ash produced by the above.

1. A method for producing “Syngas” from carbon based material in a system comprising means for feeding said material into said system, means for combustion of said material, adapted to produce Syngas, means for use of said Syngas and means for extraction of residues of said combustion, wherein said means for combustion of said material comprise:
a sealed combustion chamber for decomposing the organic molecules of said carbon based material into a mixture of gases and into ash; a device for injection of gas into said combustion chamber; a device for monitoring the quantity of gas introduced or to be introduced into said combustion chamber, for guaranteeing a correct sub-stoichiometric ratio for decomposition of said organic molecules, wherein said method comprises the following steps: a) introducing said material into the combustion chamber at a constant temperature between 300 and 600° C.; b) maintaining said material in said combustion chamber for a residence time of between 5 and 13 hours, said residence time allowing a combustion capable of decomposing the organic molecules of said material producing Syngas, continuously drawn off, and carbonous residues; c) maintaining said carbonous residues at said temperature of between 300 and 600° C. for a time between 7 and 13 hours with excess air; said excess air being capable of completely incinerating said carbonous residues; and d) using said Syngas and extraction of the ash produced by said combustion and by said incinerating.
