摘要: A method of separating metals from carbon-supported catalyst materials comprises the steps of combusting the carbon at a temperature insufficient to cause volatisation of the metal followed by reduction with hydrogen of any oxidised metal and washing with acid or water.

摘要: A supported Ziegler catalyst prepared by reacting, under substantially anhydrous conditions, a refractory oxide support material having acidic surface hydroxyl groups, e.g. silica, and an organo metallic compound, e.g. a trialkyl aluminium compound, separating any unreacted organo metallic compound and impregnating the solid product with a halogen-containing titanium compound and a halogen-containing vanadium compound. The catalyst, preferably together with a conventional Ziegler catalyst activator, e.g. an aliminium alkyl, is employed to polymerize 1-olefins, for example ethylene.
