FINDING OF KINETIC CHARACTERISTICS OF THE PROCESS CO-GASIFICATION OF HEAVY COAL TARS WITH LIGNITE AND WALNUT SHELL

Studied of co-gasification of heavy coal tars with lignite and walnut shell in the temperature ranged from  400 to 500 °С, the flow rate of oxidand (air) ranged from 0,0005 to  0,004 m3/min.  It is established that the weigth loss of the sample mixtures in the gasification process has a S-shaped. Mathematical and graphical dependences of the influence of oxidant flow rate on the values of reaction rate constants and activation energy of gasification of experimental mixtures were developed.
