1. A method for producing a catalyst for producing a hydrocarbon from a syngas, the catalyst consisting of: one of a cobalt metal or a combination of a cobalt metal and cobalt oxides; zirconium oxides; a noble metal; a catalyst support containing more than 50 mass % of silica and supporting all of them; and inevitable impurities, wherein the content of the inevitable impurities is less than or equal to 0.15 mass %, the method comprising the steps of:
loading zirconium compounds to be supported by the catalyst support by one of an impregnation method, an incipient wetness method, a precipitation method, or an ion-exchange method;
performing one of a drying treatment or a combination of drying treatment and calcination treatment of the catalyst support after loading of the zirconium compounds;
loading cobalt compounds and the noble metal simultaneously to be supported by the catalyst support; and then
performing one of a reduction treatment or a combination of a calcination treatment and a reduction treatment of the catalyst support after loading of the cobalt compounds and the noble metal, whereby the zirconium oxides exist on the catalyst support, the cobalt metal exists on the zirconium oxides, and the noble metal is present in an outer surface of the catalyst,
wherein in the reduction treatment, a hydrogen flow rate as a reducing gas is 0.1 to 40 mL/min per 1 g of catalyst.
