Abstract: A device for converting biomass with a water content of at least 50% to gaseous products includes a reactor filled at least partially with a packing including at least one filler body for accommodating supercritical water and a hydrothermal molten salt. A heater is arranged to heat up the reactor and its content. A first feeding pipe is coupled to the reactor to feed water and salt solution into the reactor. A second feeding pipe is coupled to the reactor to feed to biomass into the reactor. A discharge pipe is coupled to the reactor to discharge gaseous products from the reactor. An outlet is proved in the bottom of the reactor for removing portions of the molten salt.

Abstract: A method for converting biomass having a water content of at least 50% into gaseous products includes providing a reactor containing supercritical water and a salt melt. The salt melt includes at least one of a salt and a salt mixture. The reactor and the salt melt are heated to the reaction temperature. The biomass is heated to a preheat temperature. The biomass heated to the preheat temperature is fed into the salt melt. The biomass is heated to the reaction temperature so as to commence a conversion of the biomass into the gaseous products, so as to release from the biomass at least one additional salt into the salt melt. An amount of the salt melt containing at least a portion of the at least one additional salt is withdrawn from the reactor and the amount of the withdrawn salt melt is replaced with a fresh salt solution. The gaseous products are removed from the reactor.
