Study On Making Hydrogen By Coal Slime Via Pyrolysis And Related Catalyst

In this study, the research of hydrogen production by coal slime via pyrolysis with the related catalysts was conducted. Detailed discussion of the energy consumption in the pyrolysis process of coal slime with different water ratio was carried out. The supported monometallic sphere catalysts and supported bimetallic sphere catalysts are prepared by the method of Equivalent Volume Impregnation usingγ-Al2O3 as support. The structure and performance of the obtained catalysts was characterized by some innovative analysis instruments, such as XRD, XPS, BET, SEM and TPR, The effects of different condition on catalytic activity was also investigated by single factor experiment. The effect of catalyst outer electron configuration, d% and the geometric configuration on hydrogen production from coal slurry was illustrated qualitatively. The Ag/γ-Al2O3 sphere catalyst with higher catalytic activity was prepared in different conditions and also the supported bimetallic sphere catalyst was further prepared and the theory of "hydrogen spillover" was introduced to explain the mechanism of the making hydrogen in order to provide an evidence for the development of catalysts used making hydrogen.
