Purpose: the definition of the fundamental bases of carbonization of birch waste in wood coal and steam gasification of obtained wood coal in gas with high content of hydrogen. Research methods - standard methods for the study of solid fuels and new methods for assessment of carbonization, steam gasification, and processes of linking CO2. The processes of carbonization of clean crushed and crushed wood after impregnation by 0.5% aqueous solution of N3PO4, FeCl3, and CaCl2 and drying under modes of carbonization both with and without the use of combustion heat of volatiles are studied. Increased yield of wood coal (32%) with high content of fixed carbon (83%) is obtained from the pre-impregnated crushed birch waste by an aqueous solution of 0,5 % H3PO4. The possibility to increase the yield of wood coal by 12,8-20,9 % is shown by example of birch waste sawdust carbonization. The wood coal obtained from the crushed birch impregnated with 0,5 % aqueous solution of H3PO4 was gasified at Fuel Cell Test Installation. The minimum concentration of CO in the obtained dry gas (2,1-4,4 vol.%) is reached through the use of conversion catalyst of CO (CIP-2, 4) and lime. Technical hydrogen is obtained at the outlet of the installation at temperatures in the layer of wood coal from 660 to 757 oC. The process of carbon dioxide Ca(OH)2 absorption is studied. The obtained wood coal has greater reactivity than coal coke and medical activated charcoal. Prognosis about the object of the research - test of technologies of conversion using other types of waste biomass Product Description popup.authors Дудник О. М. Заболотний С.
