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.

CLEAN UTILIZATION OF MUNICIPAL SOLID WASTES AND ALTERNATIVE FUELS DERIVED FROM IT

For the municipal solid waste (MSW) to be used in a proper way, it is necessary to implement clean technologies capable of thermal treatment of MSW and RDF in order to produce heat and electricity while meeting current ecological requirements. Nowadays, a number of technologies for MSW/RDF thermal treating are being used worldwide. Among them, the most proven technologies, applicable for industrial introduction, have been considered while analyzing their advantages/ disadvantages accounting for local conditions of Ukraine.
