Abstract

In order to produce hydrogen for application to fuel cells, the optimal conditions for partial oxidation of propane were studied in this research. Ceria-promoted nickel-calcium hydroxyapatite catalysts (CexNi 2.5Ca10(OH)2(PO4)6; x = 0.1 - 0.3) were investigated for determination of the optimal content of ceria and ratio of O2/C3H8. With O2/C 3H8 = 1.5 (ideal reaction), ceria-promoted catalysts did not exhibit higher hydrogen yield than the unpromoted catalyst. However, as the O2/C3H8 ratio was increased to 2.0 and higher, ceria-promoted catalysts exhibited higher hydrogen yield and lower hydrocarbon by-product selectivities. The optimal conditions were determined to be content of ceria (x) of 0.1 and O2/C3H88 ratio of 2.0.
