摘要:
Process for preparation of a supported catalyst based on hydroxylated inorganic material selected from the group consisting of silica (SiO 2 ), alumina (Al 2 O 3 ), titania (TiO 2 ), zirconia (ZrO 2 ), lanthanum oxide (La 2 O 3 ) or mixtures thereof, characterized in that the hydroxylated inorganic material is contacted with organosilicon compounds selected from the group consisting of Formula 1 i.e., [(RO) y Si-[O-(RO) y Si] y -O-Si(RO) y ] or Formula 2 i.e., (RO) y -Si-R 1 -S 2-4 -R 1 -Si-(RO) y with R being alkyl and R 1 being a linear or branched alkylene having from 1 to 5 carbon atoms and y being an integer from 1 to 3.
