    摘要： The preparation is described of a Fischer-Tropsch catalytic precursor based on cobalt supported on alumina, optionally containing up to 10% by weight of silica, which comprises: a) treatment of the alumina with a silicon compound selected from those having general formula (I) Si(OR)4-nR'n (I) wherein n ranges from 1 to 3 wherein R' is selected from primary hydrocarbyl radicals having from 1 to 20 carbon atoms; wherein R is selected from primary hydrocarbyl radicals having from 1 to 6 carbon atoms ; b) drying and subsequent calcination of the modified carrier obtained at the end of step (a) thus obtaining a silanized carrier; c) subsequent deposition of cobalt on the silanized carrier obtained at the end of step (b) ; d) drying and subsequent calcination of the supported cobalt obtained at the end of step (c) thus obtaining the final catalytic precursor; the above final catalytic precursor having a content of SiO2 deriving from the compound having general formula (I) ranging from 4.5 to 10% by weight.
