Process For the Preparation of Fischer-Tropsch Catalysts With a High Mechanical, Thermal and Chemical Stability |
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)<SUB>4-n</SUB>R'<SUB>n </SUB>(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 SiO<SUB>2 </SUB>deriving from the compound having general formula (I) ranging from 4.5 to 10% by weight.
