Claim Text:
1. A catalyst for producing a hydrocarbon from a syngas in a liquid phase reaction using a slurry-bed reactor, which comprises cobalt compounds selected from the group consisting of (i) cobalt metal and (ii) cobalt metal and cobalt oxides and zirconium oxides supported by a catalyst support mainly composed of silica, wherein a content of impurities containing alkali metals and/or alkaline earth metals in the catalyst support is from 0.01 to 0.1 mass % in terms of metal, the content of each of sodium, potassium, calcium, and magnesium among the impurities contained in the catalyst support is less than or equal to 0.07 mass %; the catalyst is produced by loading said cobalt compounds and said zirconium oxides separately on said catalyst support using an impregnation method, an incipient wetness method, a precipitation method, or an ion-exchange method, wherein after loading a first of said cobalt compounds and said zirconium oxides, a drying treatment or a drying treatment and a calcination treatment are performed, and after loading a remaining of said cobalt compounds and said zirconium oxides, a reduction treatment or a calcination treatment and a reduction treatment are performed, the loading amount of cobalt metal, or cobalt metal and cobalt oxides in the catalyst is 10 to 40 mass % in terms of cobalt metal, and the loading amount of zirconium oxides is 0.03 to 0.3 in the molar ratio of Zr/Co, and the catalyst support is spherical and has a mean particle size of 20 to 250 μm.
