APPARATUS FOR PRODUCING PYROLYSIS PRODUCT Russian patent published in 2013 - IPC C10B49/22 C10B53/02 C10B49/10 

FIELD: chemistry.

SUBSTANCE: invention relates to an apparatus for producing a pyrolysis product. The apparatus includes: a pyrolysis reactor (2) for forming pyrolysis product fractions from raw material by fast pyrolysis, a separating device (4) for separating fractions from pyrolysis product fractions after pyrolysis, a condensing device (3) for condensing gaseous pyrolysis product fractions to mainly liquid pyrolysis product fractions, a combustion boiler (1) arranged in conjunction with the pyrolysis reactor, a heat carrier which is heated in the combustion boiler and is used to transfer energy, and feeding devices (5, 6, 22) for feeding raw materials into the pyrolysis reactor and the combustion boiler. The apparatus is characterised by that the separating device (4) is arranged substantially in conjunction with the pyrolysis reactor (2) for separating fractions, different from the gaseous pyrolysis product fractions, from the gaseous pyrolysis product fractions after pyrolysis, wherein fractions different from gaseous pyrolysis product fractions also include a heat carrier, and said apparatus has means (13) for feeding fractions different from the gaseous pyrolysis product fractions the from the separator (4) to the combustion boiler (1), and said apparatus has means of feeding a by-product stream, a residue stream and/or a waste stream into the combustion boiler, said streams being selected from the following streams: non-condensible gases (10) from the condensing device, gaseous combustion product fraction (19), waste stream (23) from the feed material of the pyrolysis reactor and solid substances (21) from the condensing device, and said apparatus has means (9) of feeding heat carrier from the combustion boiler (1) into the pyrolysis reactor (2), and said apparatus has means of feeding carrier gas (14) into the pyrolysis reactor (2), and said apparatus has means of preparing a mixture of feed material (6) for the pyrolysis reactor and carrier gas (14) and means of feeding heated heat carrier (9) into the mixture of feed material for the pyrolysis reactor and the carrier gas.

EFFECT: apparatus enables to avoid the need to feed additional fuel into a pyrolysis reactor, and also enables to use different process streams, streams of by-products and undesirable intermediate/end products efficiently.
