Abstract
Official abstract text for this publication.
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 T 1 and a zirconium compound at a temperature T 2 to 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 3 , 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 1 , T 2 , and T 3 satisfy conditions represented by expressions (1) to (3): T 1 ≧T 3 (1) 250° C.≦ T 2 ≦450° C. (2) 250° C.≦ T 3 ≦450° C. (3).
First claim
Opening claim text (preview).
The invention claimed is: 1. A Fischer-Tropsch synthesis catalyst, comprising: a carrier obtained by calcining a carrier precursor containing silica and a zirconia compound at a temperature of 250° C. or higher and 400° C. or lower, and cobalt oxide and/or ruthenium oxide supported on the carrier, wherein a content of the zirconia compound in the carrier precursor is 3 to 7% by mass in terms of zirconium oxide based on a total mass of the catalyst, and a mesopore volume is 0 . 35 cm 3 /g or more and a specific surface area is 130 m 2 /g or more. 2. The catalyst according to claim 1 , wherein the average pore diameter of silica is 10 to 15 nm.
