NOVELTY - A catalytically active biomass in a receiving tank (20) is subjected to cracking reaction, and the biomass is transferred to a mixer pump (24). The reaction mixture is passed into outgassing chamber of intermediate tank (31) to produce outgassed fraction and non-outgassed fraction. The outgassed fraction is cooled, and the portion (A) of non-outgassed liquid fraction is cracked. The portion (B) of non-outgassed liquid fraction in a bypass (35) is conducted to the outgassing chamber during addition of fresh biomass. Thus, thermal processing of biomass is carried out.    USE - Thermal processing of catalytically active biomass is used for producing fuel used for generating electricity, and drive motor e.g. diesel motor.    ADVANTAGE - The thermal processing of catalytically active biomass is carried out efficiently and economically without using external catalyst.    DETAILED DESCRIPTION - A catalytically active biomass in a receiving tank is subjected to cracking reaction at cracking temperature, and the biomass is transferred to a mixer pump to produce a reaction mixture. The reaction mixture is directed into an outgassing chamber of an intermediate tank to produce outgassed fraction and non-outgassed fraction. The outgassed fraction is cooled to produce fuel, and the portion (A) of non-outgassed liquid fraction is returned and subjected to the cracking temperature in the receiving tank. The portion (B) of non-outgassed liquid fraction in a bypass is conducted to the outgassing chamber of the intermediate tank during addition of fresh biomass. The settled residual material is periodically removed from the intermediate tank. Thus, thermal processing of catalytically active biomass is carried out. An INDEPENDENT CLAIM is included for apparatus for thermal processing of catalytically active biomass, which comprises a reservoir (2) accommodating biomass mixture, a transport device (7) associated to the outlet of reservoir, a receiving tank, a mixing pump which disposes the downstream of reaction mixture, an intermediate tank having outgassing chamber, an outgassing device (28) accommodated in intermediate tank, a distillation column disposed to downstream of intermediate tank, a feed line fluidity connecting an outlet of mixer pump to the outgassing device, a return line extending between the lower portion of intermediate tank and receiving tank which returns non-outgassed fraction of the mixture, a condenser which is fluidly connected to the top of distillation column for cooling an outgassed vaporized fraction of the mixture to produce fuel, and a bypass provided with bypass pump. The bypass is extended between the lower portion of intermediate tank and outgassing chamber of intermediate tank. The bypass has a port in communication with an outlet of the transport device for introduction of biomass. The condenser has an outlet for discharging fuel. The reaction mixture is heated to the cracking temperature in receiving tank, and the catalytic cracking reaction is triggered.
