Abstract

Abstract: The effect of nickel and iron naphthenate on anthracene hydrogenation by using in situ hydrogen generated through the water gas shift reaction was investigated in an autoclave. The factors of the concentration of nickel and iron naphthenate each, the mixed system of iron and nickel naphthenate were tested. The reaction conditions are follows: 400℃, 2.0MPa CO, and CO/H2O molar ratio of 1:2.5. The reaction samples were took out at different reaction time and analyzed. The results showed that iron and nickel naphthenate are catalytic active for both anthracene hydrogenation and water gas shift reaction. Nickel naphthenate is more conducive to the water gas shift reaction, while the catalytic effect of iron naphthenate on anthracene hydrogenation is more effective. The conversion of anthracene hydrogenation is the highest when the concentration of Ni in nickel naphthenate is 0.08w% and Fe in iron naphthenate is 0.05w%. There is a synergistic effect of iron and nickel naphthenate, which can effectively promote the reactions of the water gas shift and anthracene hydrogenation. Addition, the results indicated that there is a positive synergy between these two reactions.

Key words: polycyclic aromatics, naphthenate, in situ hydrogen, hydrogen storage
