NOVELTY - Method to convert a biomass reactant into synthesis gas, comprises: (a) heating biomass in first molten metal or molten ionic liquid bath at first temperature to yield dried biomass and steam and capturing steam; (b) incorporating steam into process gas; (c) heating dried biomass in second molten metal or molten ionic liquid bath at second temperature to yield product gases, tar and char; and (d) reacting product gases, tar, and char with process gas within third molten metal or molten ionic liquid bath at third temperature to yield synthesis gas via gasification and reforming reactions.    USE - The method is useful for converting biomass reactant into synthesis gas (claimed), which is useful for: firing the external burner for the reaction chamber; creating synfuel with specialized Fischer-Tropsch reactions; and generating electricity in a compact solid oxide fuel cell.    ADVANTAGE - The method: eliminates the use of reactive metallic catalysts; easily removes the non-reacting residues of biomass remain as solids; eliminates the need for an external water source; provides the device, which can be integrated into a self-powered mobile unit; enables large-scales production of syngas; and reduces the expense associated with maintaining separation devices and does not require access to water.    DETAILED DESCRIPTION - Method to convert a biomass reactant into synthesis gas, comprises: (a) heating biomass in a first molten metal or molten ionic liquid bath at a first temperature of at least 100 degrees C, but less than the decomposition temperature of the biomass, to yield dried biomass and steam, and capturing the steam; (b) incorporating the steam into process gas; (c) heating the dried biomass in a second molten metal or molten ionic liquid bath at a second temperature, where the second temperature is sufficiently high to cause flash pyrolysis of the dried biomass, to yield product gases, tar and char; and (d) reacting the product gases, tar, and char with the process gas within a third molten metal or molten ionic liquid bath at a third temperature which is greater than or equal to the second temperature within the second bath, to yield synthesis gas via gasification and reforming reactions.
