Determination of conditions for production of hydrogen and activated coal from wood waste. Development of technology for production of hydrogen briquette" popup.stage_title Head Dudnyk Oleksii, Registration Date 13-01-2011 Organization Coal Energy Technology Institute of National Academy of Sciences of Ukraine popup.description2 Object of research - processes of biomass carbonization and biofuel steam gasification. Objectives - determination of the fundamentals of spruce waste and walnut shells carbonization in wood coal and steam gasification of obtained wood coal in gas with high content of hydrogen, simultaneous production of hydrogen and activated carbon. Methods of research - standard methods for solid fuel research and new methods for assessment of carbonization, steam gasification and CO2 fixation processes. The result of impregnation of spruce waste and walnut shell samples with 0,5% water solution of N3PO4 and their carbonization was an increase in yield of wood coal by 7,1% and 19,3%, respectively. The synthesis gas containing up to 76.4 vol. % of hydrogen was obtained and 47.08% of the carbon, reacted with water steam in the bed of wood, was removed as a result of steam gasification of spruce wood coal using lime at the temperature of 760 to 790 °C. The synthesis gas containing up to 78.4 vol. % of hydrogen was obtained and 38,2% of the carbon, reacted with water steam in the bed of wood, was removed as a result of steam gasification of wood coal, produced from walnut shell, using lime at the temperature of 800 to 850 °C. The dependence of the rate of calcium hydroxide decomposition on heating temperature was determined, a new method to fall out nickel into the space inside the pores of wood coal was developed and tested, the composition of hydrogen briquettes is determined, and the dependence of hydrogen yield on the molar ratio of Ni/C are obtained. Birch wood coal was used to obtain technical hydrogen and activated charcoal with inside surface of 1,023.5 m2/g in the process of steam gasification using lime and catalyst МЦК-2,4 for CO conversion at the temperature of 650-825 °C. A new principal circuit of cogeneration steam-gas plant was developed. Forecast assumptions about the development of the object of research - test of conversion technologies using other biomass waste, modernization of existing facilities, creation of new clean solid fuels.
