Abstract
For the production of hydrogen, partial oxidation of n-tetradecane (TD), which is a representative component of diesel, was carried out in a fixed-bed reactor with the O/C ratio of 1.25 by employing ceria-promoted Ni-substituted hydrotalcite-derived catalysts (CexNi3Mg3Al2(OH)16(CO3); x=0.15~0.6). TD was fully converted above 973 K with no condensable products and C3 and higher hydrocarbons formed were negligible. The Ce/Ni ratio of 0.3/3 showed the best H2 yield above 90% at 1,173 K. However, when the Ce/Ni ratio was higher than 0.3/3, the H2 yield was slightly decreased. In long-term tests, ceria-promoted catalyst showed good catalytic stability for 30 h.
