    摘要: The invention relates to a process for the preparation of a titanium catalyst which process comprises: (a) drying a silica carrier at a temperature of from 300 to 800° C. to obtain a dried carrier; (b) contacting the dried carrier obtained in step (a) with a gas stream containing titanium halide at a temperature in the range from 125° C. lower to 125° C. higher than the drying temperature of step (a) and at a pressure higher than 0.8 bar to obtain an impregnated carrier; (c) calcining the impregnated carrier obtained in step (b) to obtain the titanium catalyst.
