Conversion of coken coal and peat volatiles in gas with high content of hydrogen. Hydrogen production from coken coal" 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 Research object - processes of coke steam gasification and steam conversion of volatiles and cokes of Ukrainian coking coal and peat. Objectives - determination of indices of steam conversion of volatiles and cokes of Ukrainian coking coal and peat in plants for hydrogen production. Methods of research - standard methods for solid fuel research and new methods for assessment of processes of Ukrainian coking coal and peat conversion. The data obtained on 1-4 stages were generalized. The hydrogen of purity up to 98% was produced from the cokes of Ukrainian bituminous coal of Lviv-Volyn deposit, brown coal of Korostyshev Zhytomyr region deposit, and methane. In 2010, the peat of Rivne region deposit and coking coal of Donetsk coal basin were used for steam conversion. The dynamics of peat devolatilization was studied and peat coal was obtained. An increase in hydrogen content in dry gas up to 72.04 vol. % when using peat and to 83.74 vol. % when using coking coal was reached due to steam conversion of volatiles on a lime bed. 49.58% of carbon, reacted with steam water, was fixed during the steam gasification of peat coke in the absorber bed. Coke of coking coal was used to produce hydrogen by the circuit: the steam gasifier (with lime), water shift reactor (with catalysts of CO conversion), and CO2 absorption reactor (with a solution of monoethanolamin). At the exit of the installation has been received from Hydrogen with purity of 93,2-94,7% was obtained at the installation outlet. A new process of combustion and gasification of solid fuels in circulating fluidized bed under pressure for steam-gas plant on fuel cells is developed. Forecast assumptions about the development of the object of research - modernization of the Fuel Cell Test Installation, creation of a new pilot plant for hydrogen production using fuel cells.
