Due to its abundant resources coal will play an important part in world energy balance in the years to come. One ofthe most interesting ways ofits conversion is the process of hydrogasification. However, the low coal reactivity with hydrogen constitutes a problem. Therefore, catalysts required for this process must be selected. The paper presents the results of kinetics examination of hard coal with high volatile matter contents. The first series ofexaminations involved comparison ofhydogasification kinetics for raw coal and for coal with reduced contents of ash and pyrite. In the former case much higher yields of hydrocarbons were observed, mainly due to a higher yield of methane. In the second series of examinations, coal with additions of pyrite, iron - oxide (Il\} and elementary sulphur were observed to have a beneficial effect on the process of hydrogasification. In this case, the increase in the rate of reaction occurred at temperatures exceeding 1150 K. The iron - oxide (Il) alone was reported to have no influence on hydrogasification reaction. The other additives increased the yield ofmethane, not exerting any influence on other products ofhydrogasification process.}, type={Artykuł}, title={Effect of iron - and sulphur compounds on the kinetics of hard coal hydrogasification}, URL={http://ochroma.man.poznan.pl/Content/132596/PDF/6_GSM_18_2_2002_Porada_Wplyw.pdf}, keywords={Coal, hydrogasification, kinetics, catalysts}, }
