NOVELTY - Rapid pyrolysis of biomass and hydrocarbon-containing products involves loading feedstock in pyrolytic chamber, pyrolysis arranged within pyrolytic chamber heating elements, producing output of obtained steam-gas mixture and unloading obtained solid product, where pyrolysis is achieved under action of sequence of thermal pulses, transferred and heated by electric pulse heating elements, placed in pyrolytic chamber so that its volume is divided in locally heated loops.    USE - The method or device is useful for rapid pyrolysis of biomass and hydrocarbon-containing products (claimed).    DETAILED DESCRIPTION - Rapid pyrolysis of biomass and hydrocarbon-containing products involves loading feedstock in pyrolytic chamber, pyrolysis arranged within pyrolytic chamber heating elements, producing output of obtained steam-gas mixture and unloading obtained solid product, where pyrolysis is achieved under action of sequence of thermal pulses, transferred and heated by electric pulse heating elements, placed in pyrolytic chamber so that its volume is divided in locally heated loops, where for power supply of heating elements, current source with electronic switch is used, where a duration of electric pulse comprises 0.1-1.0 second, power of electric pulse is such during pulse to that provide heating element to temperature of 450-500 degrees C, time interval between electric pulses is selected so as provide possibility of cooling heating element in gap between pulses to temperature of 200-250 degrees C, where output of obtained steam-gas mixture is achieved through opening in walls of pyrolytic chamber, and condensation of its steam fraction is accomplished on condensers, which are cooled surfaces, arranged at smallest possible distance from outer walls of pyrolytic chamber. An INDEPENDENT CLAIM is included for device for performing the method above comprising loading container, pyrolytic chamber, container for receiving liquid and solid products and placed inside pyrolytic chamber heating elements, where heating elements are connected to current source with electronic switch and are arranged in volume of pyrolytic chamber so that its volume is divided in locally heated loops, where heating elements are made from corrosion- and thermo-resistant current-conducting material with high specific electrical resistance, side walls of pyrolytic chamber have opening for output of obtained with pyrolysis steam-gas mixture, and outside the pyrolytic chamber at smallest possible distance from its walls condensers are arranged, which are cooled surfaces.
