CHEMICAL ANALYSIS OF THE COMPOSITION OF GAS-PHASE AND LIQUID PRODUCTS OF GASIFICATION OF LOW-CALORIE SOLID-PHASE BIOFUEL MIXTURES IN A SUPERADIABATIC REACTOR

The authors have given results of experimental investigations into the gasifi cation of a solid composite fuel in a superadiabatic reactor with a water-cooled condenser making it possible to collect and analyze gas-phase and liquid gasifi cation products. A detailed study has been made of the processes of gasifi cation of low-calorie solid-fuel mixtures based on wood chips with a high content of water (as high as 37.1%). In the experiments, full, in practice, conversion of the solid fuel into gaseous and liquid-phase products was observed. An analysis of the gas-phase gasifi cation products and nitrogen oxides was made using electrochemical gas analyzers. The composition of the liquid-phase products was analyzed by the mass-spectrometry method and the high content of organic substances (phenols, organic acids, and ethers) in them was shown. The obtained data confi rm the promising nature of gasifi - cation of low-calorie solid-fuel mixtures in a superadiabatic regime as an energy-saving and environmentally safe method to recycle and utilize wood waste, and also components of municipal solid waste.
