GASIFICATION DEVICE FOR THE VALORIZATION OF SUBSTANCES CONTAINED IN A CARBONACEOUS FEEDSTOCK MATERIAL

摘要

Gasification device (10) for the valorization of substances contained in a carbonaceous feedstock material, said device comprising a reactor body (11) in which a first and a second end (11a, 11b) are defined, said reactor body being provided with a corresponding inlet (13) for said feedstock material (Fs) to be treated and with at least a first inlet (15) for introducing feed gases (G1, G2) into said body (11), wherein said device is configured to perform at least two treatment stages (S1, S2) for the gasification of said feedstock material (Fs) in order to obtain a syngas (Gu), wherein said device (10) further comprises: a gas distribution system (19) associated with said first inlet (15) in order to distribute the feed gases (Gl, G2) inside the body (11) and comprising in turn mixing means (27) for mixing said gases (Gl, G2) with said feedstock material (Fs) in order to obtain a first gasification of said feedstock material (Fs) in a first treatment stage (SI); first dissociation means (39) comprising first grids (39) and first heat storage means (47) and second dissociation means (53) comprising second grids (53) and second heat storage means (61) for performing a treatment of gasification of the molecules of the feedstock material (Fs) that have not been gasified in the first treatment stage (S1); a purification system (63) for separating the gaseous fraction obtained from said treatment stages (S1, S2) from ashes; and wherein said gas distribution system (19), said first and second dissociation means (39, 53) and said purification system (63) are arranged in cascade from the first to the second end (11a, 11b) of the body (11) in order to promote a process of co-current gasification.
