System and method for continuous production of renewable liquid fuel

A system for carbonizing biomass, comprising:

• a mixer configured to receive an amount of uncarbonized solid biomass particles or chunks and a biofuel, the biofuel providing for thermal conductance between the uncarbonized solid biomass particles or chunks, the mixer combining the amount of uncarbonized solid biomass and the amount of biofuel into a batch of blend;
• a sealable container configured to receive the blend;
• a lid configured to mount on a top opening of the sealable container to close the sealable container in a sealed state;
• a heating channel configured to circulate a first molten salt heat exchange medium around an exterior wall of the sealable container such that the molten salt heat exchange medium is separated from the batch of blend contained in an interior of the sealable container by the wall of the sealable container;
• and
• a heat source for heating the circulating first molten salt heat exchange medium.
