摘要: A process for producing a supported cobalt-based Fischer-Tropsch synthesis catalyst includes, in a first activation stage, treating a particulate catalyst precursor with a reducing gas, at a heating rate, HR1, until the precursor has reached a temperature, T1, where 80° C.≦T1≦180° C., to obtain a partially treated precursor. In a second activation stage, the partially treated precursor is treated with a reducing gas, at a heating rate, HR2, where 0≦HR2 HR2 until the partially reduced precursor reaches a temperature, T2. The partially reduced precursor is maintained at T2 for a time, t2, where t2 is from 0 to 20 hours, to obtain an activated catalyst.

摘要: A process for preparing a cobalt based Fischer-Tropsch synthesis catalyst precursor includes introducing a multi-functional carboxylic acid having the general formula (1) HOOC—C*R1C*R2—COOH (1) or a precursor thereof, where C* in each of C*Ri and C*R2 is a sp2 carbon, and R1 and R2 are the same or different, and are each selected from the group consisting of hydrogen and an organic group, into and/or onto a particulate catalyst support. The ratio of the quantity of multifunctional carboxylic acid used relative to the support surface area is at least 0.3 μmol carboxylic acid/m2 of support surface area. Simultaneously with the introduction of the carboxylic acid into and/or onto the catalyst support, or subsequent thereto, a cobalt compound is introduced into and/or onto the catalyst support. The impregnated support is calcined to obtain the cobalt based Fischer-Tropsch synthesis catalyst precursor.
