METHOD AND APPARATUS FOR PRODUCING RAW MATERIAL FOR BIOFUEL PRODUCTION

摘要

A method for producing a torrefaction gas product (425) from torrefaction gases, wherein the torrefaction gas product (425) is suitable as raw material for biofuel production. The method comprises receiving torrefaction gases, the torrefaction gases being produced by processing biomass in a torrefaction process and condensing the torrefaction gases to a torrefaction gas condensate, the torrefaction gas condensate comprising the torrefaction gas product (425). An embodiment comprises cooling the torrefaction gases to a condensing temperature, wherein the condensing temperature is between 10 ° C and 40 ° C. In addition, raw material for biofuel production, the raw material having been produced by the method. Furthermore, use of condenser (410) for condensing the torrefaction gases to a torrefaction gas condensate. Still further, an apparatus for producing the torrefaction gas product (425) from torrefaction gases. The apparatus comprises a condenser (410) arranged to condense the torrefaction gases. In an embodiment, the condenser (410) arranged to cool the torrefaction gases to a condensing temperature, wherein the condensing temperature is between 10 ° C and 40 ° C.
