Method for preparing a catalyst using a quick-drying step and use of said catalyst in Fischer-Tropsch synthesis

摘要

Preparing a catalyst comprising an active phase including at least one group VIII metal consisting of cobalt, nickel, ruthenium and iron and an oxide support, comprises impregnating an oxide support, drying the impregnated oxide support using a gas for 1 second to 1 minute, where the impregnated oxide support is subjected in the step to a temperature rise gradient of 250-600[deg] C/minutes, and calcining the dried and impregnated oxide support. An independent claim is included for Fischer-Tropsch synthesizing of hydrocarbon from a mixture of carbon and hydrogen comprising preparing the catalyst, where the Fischer-Tropsch synthesizing method is carried out at a temperature of 190-240[deg] C, a total pressure of 1-5 MPa and with a molar ratio of hydrogen/carbon monoxide is 1.5-2.5.
