METHOD OF DETERMINING DEPENDENCY OF OUTPUT OF POLYFRACTIONAL SOLID FUEL SEMICOKING PRODUCTS ON HEATING TEMPERATURE Russian patent published in 2013 - IPC C10B53/00 C10B57/14 

FIELD: chemistry.

SUBSTANCE: invention relates to investigation of processes of thermal decomposition of solid fuels and can be used in chemical and fuel industry. The method of determining the dependency of output of polyfractional solid fuel semicoking products on heating temperature involves placing the starting fuel in an annular reaction volume between two heat-conducting surfaces; external and internal heating of the solid fuel through the heat-conducting surfaces without access to oxygen to a given final temperature; measuring heating temperature at different points on the cross-section of the annular volume at a different depth; recording the given final heating temperature of the fuel as the average arithmetic value of readings of all heat sensors; heat-insulating the collector; maintaining temperature higher than 200°C in the top part of the reaction volume and keeping final temperature of the process constant until the release of gas stops completely; and removing the formed gaseous products through the collector into a condensation system; insulating the inner volume of the vessel from the condensation system and determining output of semicoking products.

EFFECT: invention increases accuracy of determining output of semicoking products.
