METHOD OF THERMOCHEMICAL CONVERSION OF ORGANIC CONTAINING RAW MATERIAL AND THE COMPLEX OF THERMOCHEMICAL CONVERSION INCLUDING THE REJECTOR OF CONJUGATED HEATING FOR ITS IMPLEMENTATION Russian patent published in 2018 - IPC C10B47/00 C10B47/30 F23G5/20 

FIELD: heat power engineering; timber industry.

SUBSTANCE: group of inventions relates to processing of organo-containing raw materials by means of its thermochemical pyrolysis and conversion with the extraction of liquid hydrocarbons for the secondary use of processed products and can find its application in heat power engineering, in chemical and timber industries. Method for thermochemical conversion of an organo-containing feedstock involves pre-drying the air with a temperature of 80–90 °C. Raw material is then subjected to rapid ablation low-temperature pyrolysis without air access in the drum-type reactor of indirect heating under activation conditions due to the organized friction of organic particles against the drum wall. Reactor is placed inclined to the horizon at an angle of 1–5 degrees with the possibility of rotating its drum at a frequency of 2–5 rpm, and inside the drum is provided with chains. In this case, a temperature of 470–500 °C is maintained in the reactor drum, a vacuum of 5–10 mm of water column is created, the time of gas in the heated zone is less than 15 seconds is insured and in the final cycle of the process, prior to unloading, the partial pressure of the synthesis products is forcibly reduced, for this purpose, 10–15 % of the volume of gaseous hydrocarbons is introduced into the discharge unit. Dissipative zones are organized for combustion products. Vapor-gas mixture obtained during the pyrolysis process is sent to the condenser through the catalytic reactor, after which the gas fraction of the conversion products is used to heat the pyrolysis reactor, and the resulting liquid fuel is sent to the collector.

EFFECT: technical result is the stabilization of the quality of liquid pyrolysis products, increasing the reliability and completeness of the process.
