The results of the research on the process of gasification of coal mixture in a closed system was evaluated in this article. The method presented includes oxygen-free gasification of coal at high pressure and its thermal degradation. Hydrogen is a gasifying factor. Gas containing, among others, methane, carbon dioxide, carbon monoxide, hydrogen is obtained as a result of reaction. Fossil coal as a chemical and energetic raw material is very significant in the process of demand for energy. Due to more and more difficult access to petroleum and natural gas, as well as growing prices, fossil fuels are becoming economically attractive. However, the works on more effective and environmentally friendly methods of energetic use of coal - including its gassing - should be continued. The use of hydrogen during coal gasification allows to get emission-free fuel gas, having better energetic properties than primal raw material.The laboratory site was built and consisted of: 4,5dm3 reactor with a heating system, system of supply reactor with hydrogen and rinsing with argon and cooling system. The results of hydrogasification of coal with specific parameters, for selected time intervals were presented in this article. The efficiency of hydrogasification depending on the type of applied coal was assessed. Powdered charcoal, meeting the norm of German Committee for Standardization DIN EN1860 2 with a number 3H020, hard coal and lignite coal, as well as their mixtures were applied during the research.
