| 摘要 | A method of preparing a catalyst comprising contacting an acidic colloidal silica suspension with a titanium-containing compound to form a mixture, adjusting the pH of mixture to about neutral to form a catalyst support, and contacting the catalyst support with chromium-containing compound to from a chromium-supported catalyst. A catalyst support prepared by contacting a colloidal silica suspension and a titanium-containing compound under acidic conditions to form a mixture, and contacting the mixture with a basic material in an amount sufficient to increase the pH of the mixture to about 7. | ||
