METHOD AND DEVICE FOR THERMOCHEMICAL TREATMENT OF SOLID ORGANIC MATERIALS Russian patent published in 2004 - IPC

FIELD: treatment of polymeric-structure solid materials including carbohydrate or hydrocarbon raw materials to produce energy and various kinds of fuel.

SUBSTANCE: proposed method involves contact heating without oxygen access and transfer of part of solid organic material to vapor phase followed by condensation of some products of treatment; in the process organic material is heated by forcing solid organic material through channel whose sectional area reduces in direction of solid material flow formed by heated surface of material having high thermal conductivity; temperature in converging channel is raised in direction of solid organic material from 400 to 750 °C, and gasified products of thermochemical treatment having different gasification temperatures are taken from respective temperature zones of channel on flow path of organic material. Process of fractional separation of products goes on continuously in the course of steam-gas phase formation.

EFFECT: simplified design and enlarged service life of equipment.
