1. A hydrocarbon synthesis catalyst comprising:
an unreduced form comprising:
a) Fe as catalytically active metal,
b) a first promoter comprising an alkali metal and/or an alkaline-earth metal, the alkali metal and/or alkaline-earth metal being present in a combined amount of 0.1 to 1.0 g/100 g Fe,
c) a second promoter comprising a metalloid, the metalloid being antimony, present in an amount of 0.03 to 0.2 g/100 g Fe,
d) a surface area of 80 m2/g or less, and
e) a weight ratio of the first promoter to the second promoter of 0.8:1 to 20:1; and
a reduced form comprising:
a chemical bond between the at least one metal of the first promoter and the metalloid of the second promoter, and wherein at least 75 wt. % of the Fe is in the zero oxidation state.
