CATALYTIC MODIFICATION OF PYROLYTIC VAPOUR Russian patent published in 2019 - IPC C10G1/06 C10G3/00 C10B49/22 C10B53/00 C10J3/12 C10K1/00 C10K3/02 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing a crude condensate from pyrolysable material. Method includes fuel combustion in boiler with fluidized bed and heating of granular material; transfer of at least heated granular material or other heated granular material into a pyrolysis reactor for pyrolysis in a reactor; pyrolysis of pyrolysable material; transfer of at least pyrolytic steam through a catalyst layer comprising a catalyst material; and feeding at least part of the formed by-products back into the method, into the upstream section, resulting in a product of catalytic treatment of pyrolytic vapour effective in terms of resource saving manner.

EFFECT: technical result is an increase in the economic efficiency of the pyrolysis method, through which high-quality pyrolysis products can be obtained, high efficiency in terms of the amount of raw materials used and heat fluxes obtained and used, improved method in terms of the service life of the catalyst used in the method.
