Purpose - determination of process performance of thermolysis, volatile and Ukrainian BC coke SC in the installations for hydrogen production. Methods - standard methods for the study of solid fuels and new methods for assessment of Ukrainian BC SC. Recent researches of organic fuel conversion into hydrogen are reviewed. The processes of thermolysis and SC of Zhitomirsky BC volatile are studied. Experiment shows that the use of volatile SC three times reduced the time of BC carbonization in comparison with thermolysis. BC coke was used to obtain hydrogen by two circuits: 1) steam gasifier with medium-temperature catalyst of CO absorption within the layer of lime, 2) steam gasifier (with lime), water shift reactor (with catalyst of CO conversion) and CO2 absorption reactor (with solution of monoethanolamine). Synthesis gas containing over 80 vol. % of hydrogen (technical hydrogen) was obtained at the gasifier outlet by the circuit (1). 59.3% of carbon reacted with steam was removed by absorber in the gasifier. Hydrogen with purity of 94.7-96.2 % was obtained at the installation outlet by the circuit (2). 89.7% of carbon, reacted with steam in the gasifier, was removed in the installation. Prognosis about the object of the research - test of technologies of conversion using other types of solid fuel, modernization of existing installation for testing fuel cells.
