Abstract

1505818 Polymerisation catalyst BRITISH PETROLEUM CO Ltd 21 May 1975 [11 June 1974] 25833/74 Heading BIE [Also in Division C3] An olefin-polymerisation catalyst is prepared by (i) heating a support comprising silica, alumina, thoria, zirconia or composites thereof, having chemisorbed surface hydroxyl groups, with one or more compounds of metals selected from B, Cu, Mg, Al, Zr, Th, V, Cr, Mo, W, Mn, Fe, Co, Ni, Zn, Ga, Sn, Pb or La at a temperature of 150-1200‹C, and (ii) incorporating in the product under substantially anhydrous conditions a chromium compound and heating at 100-900‹C to activate the catalyst. The support may be reacted with the metal compound(s) in two steps with an intermediate rehydroxylation of the support with a hydroxyl-containing compound, e.g. water or an alcohol. The examples relate to silica-supported compositions.
