A process for producing a Fischer-Tropsch synthesis catalyst according to the present invention comprises a step of calcining a carrier precursor containing silica calcined at a temperature Tand a zirconium compound at a temperature Tto obtain a carrier; and a step of calcining a catalyst precursor containing the carrier and a cobalt compound and/or a ruthenium compound at a temperature T, wherein the content of the zirconium compound in the carrier precursor is 0.01 to 7% by mass in terms of zirconium oxide based on the total mass of the catalyst, and T, T, and Tsatisfy conditions represented by expressions (1) to (3):&#x2003;&#x2003;(1)250&#xb0; C.&#x2266;&#x2266;450&#xb0; C.&#x2003;&#x2003;(2)250&#xb0; C.&#x2266;&#x2266;450&#xb0; C.&#x2003;&#x2003;(3).

Fischer-tropsch synthesis catalyst, method for producing same, and method for producing hydrocarbon

The present invention relates to a novel catalyst which has a molecular sieving effect (or shape selectivity) and has excellent catalytic activity, and particularly to a catalyst which includes a core made of a zeolite particle having a particle size of not more than 10 &#x3bc;m and a zeolite layer covering the core, wherein as measured by X-ray photoelectron spectroscopy, an outermost surface of the catalyst has a silica/alumina molar ratio of not less than 800, the core made of the zeolite particle has an average silica/alumina molar ratio of not more than 300, and the zeolite layer has an aluminum concentration increasing inward from an outer surface of the catalyst.
