METHOD AND DEVICE FOR THERMOCHEMICAL PROCESSING OF SOLID ORGANIC SUBSTANCE Russian patent published in 2008 - IPC C10B51/00 C10G1/00 B09B3/00 

FIELD: chemistry, organic.

SUBSTANCE: present invention is related to a method of thermochemical processing of a solid, ground organic substance and to a device for implementation of the method. The method comprises heating in a thermochemical reactor consisting of two chambers, without oxygen access, with conversion of a portion of solid organic substance to the vapour phase and subsequent condensation of a portion of processing products, and is characterized by the fact that, in the primary chamber, the following takes place: partial termochemical decomposition of organic matter particles, equalisation of particle sizes in at least one of three dimensions, and particle surface carbonisation by heating and mechanical processing in an organic particles flow moving in a thin layer between two heated surfaces of working members moving in the direction of the organic substance flow at different speeds while producing mechanical pressure on the organic substance particles on the side of contacting them, facing each other and heated to 300...400°C surfaces of working members; in the secondary chamber, at a temperature of 500...850°C, the final stage of thermochemical decomposition of organic substance particles takes place, the particles having approximately the same sizes at least in one of three dimensions, both due to direct thermal contact with a heated surface of one of the working members made of material having a high heat conductance coefficient and good elastic properties and due to exposure to electromagnetic emission in the visible and IR range, intensity of the thermochemical decomposition being strengthened by making organic substance particles change their orientation relative to the incident electromagnetic emission under action of mechanical vibration. The use of this method allows an increase in the process productivity and the degree of solid organic material conversion to liquid and gaseous products.

EFFECT: higher productivity of solid organic material conversion to liquid and gaseous products.
