With many advantages, hydrogen is considered as the fuel of the future. But there is no natural resourceof hydrogen and it must be produced by other kinds of energy. As for the primary energy, nuclear energy is a promis-ingalternative. Using heat from nuclear reactor to produce hydrogen is receiving more and more concerns in recentyears. This paper mainly emphasizes the study of the direct contact pyrolysis (DCP) of methane using heat from nu-clearreactor. A facility was designed to investigate the efficiency of DCP process in certain conditions. The experi-mentalresults show that this process produces only hydrogen and carbon. The conversion efficiency increases withtemperature and residence time, but decreases as flow rate increases. The highest efficiency of DCP obtained in thisexperiment is about 22%.
