Process and device for converting biomass to gaseous products

A process for converting biomass with a water content of at least 50% to gaseous products, comprising:

• a) filling a reactor containing a packing comprising at least one filler body with a molten salt comprised of one of a salt or a salt mixture having a melting point below a reaction temperature required for converting the biomass to gaseous products;
• b) heating the molten salt so that the molten salt spreads out inside the reactor over the packing with the at least one filler body;
• c) feeding a watery biomass into the reactor, wherein the biomass is then heated up to the reaction temperature and comes in contact with the molten salt on the packing with the at least one filler body, thereby resulting in the conversion of the biomass to gaseous products and causing additional salts from the biomass to be bonded to the molten salt;
• d) removing portions of the molten salt enriched with additional salts from the biomass from the reactor and replacing of the removed portion of molten salt with a fresh salt solution;
• e) removing the gaseous products from the reactor via a discharge pipe;
• and
• f) implement the process steps above the critical water pressure.
