NOVELTY - In the fast pyrolytic liquid production, the rotor: is subjected to centrifugal forces greater than 2000 times the force of gravity; has an inner diameter of 0.01-5 m; is rotated at 200 rpm; and has a gas phase retention time of more than 5 seconds. The outer wall of the chamber heats (350-700degreesC) the biomass while decomposition to carry out ablative pyrolysis at or near the outer wall. The ratio between the diameter of the rotor and the chamber is 0.5. The vapors are diffused into a condenser chamber and partially condensed in a primary condenser. The heat is transported by conduction.    USE - The invention deals with production of pyrolysis liquid, char and pyrolysis gas from biomass.    ADVANTAGE - Higher yield of pyrolytic liquid, cost effective and efficient pyrolytic liquid production. Improved efficiency of the biomass collection by the mobile unit.    DETAILED DESCRIPTION - The pyrolytic liquid production further comprises separating the pyrolysis vapors and char, conveying the vapors and fine particle char away from the chamber through openings, condensing the vapors to obtain pyrolysis liquid and pyrolysis gas, forcing the vapors via a channel under a pressure gradient by the rotation, recycling the particle-free vapors to the chamber through opening near intake ports of the chamber, combusting pyrolysis gas, char, liquid or hydrocarbon in a furnace, collecting the biomass by a mobile unit, drying the gas from the partial condensation, mixing the resulting liquid phase consisting water with the char to obtain slurry, distributing the slurry over the growth site and/or collecting it for further processing or combustion, leading the vapors formed in the process of contacting hot char with liquid to a tertiary condenser, and admixing the vapor with liquid product produced by the condenser. The chamber has an annular cross-section, and the condenser chamber is arranged centrally in the rotor. The vapors are diffused through an inner wall of the chamber and the fine particles are conveyed into the channel by conveyor and/or gravity action. The condenser chamber accommodates a packing material. A pyrolysis liquid or a hydrocarbon immiscible with pyrolysis liquid is led into the condenser chamber via a pipe arranged coaxially within the condenser chamber. The gas phase and the biomass, char, pyrolysis vapors are forced in a peripheral direction by rotor blade arranged in the centrifuge chamber. The centrifuge is arranged coaxially within a furnace and comprised in a mobile unit. A portion of pyrolysis gas as fuel is conveyed to furnace and/or for an engine for propelling the mobile unit. INDEPENDENT CLAIMS are included for:    (1) a fast pyrolysis apparatus for producing pyrolysis liquid, char and pyrolysis gas from biomass; and    (2) a mobile unit.    DESCRIPTION OF DRAWING(S) - The figure shows pyrolysis apparatus for producing pyrolysis liquid, char and pyrolysis gas from biomass.
