Abstract:
1. A catalyst for catalytic partial oxidation of hydrocarbon, which comprises a carrier comprising an inorganic oxide, a first constituent element of the carrier comprising an inorganic oxide being Al, the carrier containing Al in an amount of from 30% to 90% per unit weight in terms of Al 2 O 3 , the carrier comprising an inorganic oxide further comprising oxides of at least two elements selected from the group consisting of elements belonging to alkaline earth metals, elements belonging to rare earth metals, and the elements Sc, Bi, Zr, Si and Ti, in addition to the first constituent element, the carrier comprising the inorganic oxide contains zirconia stabilized by at least one element selected from Y Ce, Ca, Mg, Sc and Sm, the carrier also comprising an active metal supported thereon, the catalyst having pores, wherein, in a pore distribution of the pores in the catalyst, the total volume of pores having a pore diameter of from 0.1 μm to less than 1.0 μm defining a first range is 32% or more of the whole pore volume, and the total volume of pores having a pore diameter of from 1.0 μm to less than 10 μm defining a second range is 14% or more of the whole pore volume, wherein the catalyst is used in producing a synthesis gas containing carbon monoxide and hydrogen by adding at least oxygen and steam to a raw material hydrocarbon containing at least one of methane and a light hydrocarbon having 2 or more carbon atoms, thereby subjecting the raw material hydrocarbon to catalytic partial oxidation.
