NOVELTY - The method for producing biofuel comprises producing a biomass-charge for processing and generating cracking-gas by pressure-less heating of the biomass charge, passing the generated gas through the biomass charge to separate a catalyst from the biomass charge, liquefying the catalyst-containing gas to a distillate, and collecting the distillate. The heating of the biomass charge is carried out in three steps which includes heating at low processing temperature, average processing temperature and highest temperature in first, second and third steps, respectively.    USE - The method useful for producing biofuel.    ADVANTAGE - The method ensures production of biofuel with high quality and quantity in simple and cost effective manner.    DETAILED DESCRIPTION - The method for producing biofuel comprises producing a biomass-charge for processing and generating cracking-gas by pressure-less heating of the biomass charge, passing the generated gas through the biomass charge to separate a catalyst from the biomass charge, liquefying the catalyst-containing gas to a distillate, and collecting the distillate. The heating of the biomass charge is carried out in three steps which includes heating at low processing temperature, average processing temperature and highest temperature in first, second and third steps, respectively. The catalysts in the three catalyzed-steps are subdivided, of which the catalyst used in the first and last stages are heated in the flow direction of the produced gas simultaneously with the heating of the biomass charge and the catalyst step arranged between the first and last steps remains unheated. For processing the biomass charge, dry biomass is mixed with organic residue such as vegetable oil and carrier oil. The biomass charge is added with sulfuric acid. The utilized catalyst is reprocessed by heating on a predetermined cleaning temperature, which is higher than the highest process temperature used in the third step. An INDEPENDENT CLAIM is included for a device for producing biofuel.    DESCRIPTION OF DRAWING(S) - The diagram shows a simplified schematic representation of a device for producing biofuel.
