The gases formed are recovered, and are contacted with a second molten salt bath optionally different from said first bath and, at the outlet of said second bath, the recovered gases are either stored optionally under pressure, or reinjected into said first bath or said second bath.

PROCESS FOR GASIFYING A CARBON-CONTAINING SUBSTANCE BY MOLTEN SALT CATALYSIS, AND ASSOCIATED PLANT
The present invention concerns a process for gasifying a solid, carbon-containing substance by molten salt catalysis, wherein: - said carbon-containing substance in the presence of air and for a predetermined time is contacted with a first bath of molten salts which comprises at least one chloride salt selected from NaCl, MgCl2, CaCl2, KCl and FeCl2 and which has a melting temperature of not less than 300°C, a density of more than 1 as measured in the liquid state and at atmospheric pressure, and a heat capacity per unit mass, as measured in the liquid state and at atmospheric pressure, which is lower than the heat capacity per unit mass of water as measured at a temperature of 25°C and at atmospheric pressure, and - the gases formed are recovered. Said gases recovered are, characteristically, contacted with a second bath of molten salts, optionally different from said first bath, and at the exit from said second bath, the gases are either stored, optionally under pressure, or reinjected into said first bath or said second bath. The present invention also concerns a plant for implementing the process. 20
