Method for decomposing organic raw material, and a method for producing a liquid fuel, a solid fuel, or activated charcoal using the same

A method for producing a liquid fuel, comprising:

• a raw material supply step of supplying an organic raw material containing biomass and/or organic polymer waste, and an artificial carbon particle other than activated charcoal to a fluidized-bed-type decomposition apparatus,
• a decomposition step of decomposing the organic raw material into a non-solid decomposition component and a solid residue while fluidizing the artificial carbon particle with introducing an inert gas containing oxygen at a concentration of 3% by volume or less as a carrier gas to the fluidized-bed-type decomposition apparatus, to discharge the non-solid decomposition component with the carrier gas as well as to discharge the solid residue separately from the non-solid decomposition component,
• a gas-liquid separation step of separating the non-solid decomposition component discharged from the fluidized-bed-type decomposition apparatus into an off-gas component and a decomposed oil by cooling,
• a step of reforming the decomposed oil by conducting at least one type of reforming treatment selected from dehydrogenation, conversion, isomerization, hydrogenation, hydrocracking, and hydrotreating under the presence of a catalyst, to produce reformate, and
• a step of distilling the reformate, wherein
• the artificial carbon particle is a granular carbonized product.
