Abstract

LPG has good infrastructure and is anticipated to be used for production of hydrogen, and n-butane which constitutes a main component of LPG for vehicles. Partial oxidation (POX) of n-butane is investigated in this research by employing ceria-promoted Ni/calcium hydroxyapatite catalysts (Ce _x Ni_2.5/Ca₁₀(OH)₂(PO₄)₆ x=0.1-0.3) which have recently been reported to exhibit good catalytic performance in POX of methane and propane. The experiments were carried out with changing ceria content, O₂/n-C₄H₁₀ ratio and reaction temperature. As the O₂/n-C₄H₁₀ ratio increased up to 2.75, the n-C₄H₁₀ conversion and H ₂ yield increased and the selectivity of methane and other hydrocarbons decreased. But with O₂/n-C₄H ₁₀=3.0, the n-C₄H₁₀ conversion and H ₂ yield decreased. Ce_0.1Ni_2.5/Ca ₁₀(OH)₂(PO₄)₆ showed the highest n-C₄H₁₀ conversion and H₂ yield on the whole. In durability tests, higher hydrogen yield and better catalyst stability were obtained with the O₂/n-C₄H₁₀ ratio of 2.75 than with the ratio of 2.5.
