Method for preparing catalyst |
| abstract |
A method of preparing a catalyst comprising: a) contacting (i) a silica support, (ii) a titanium oxide compound, (iii) a chromium-containing compound and (iv) an optional solvent to form a first aqueous mixture, It comprises a precatalyst and a reaction medium containing from about 1 wt% to about 99 wt% water; b) thermally treating the precatalyst by heating to a temperature of from about 400°C to about 1000°C for a period of from about 1 minute to about 24 hours , to form a catalyst. A method of preparing a catalyst comprising contacting a hydrated support material comprising silica with a chromium-containing compound to form a first aqueous mixture comprising a chromated support; contacting the first aqueous mixture comprising a chromated support with a solvent comprising (i) contacting the solution of (ii) the titanyl compound to form a second aqueous mixture comprising the precatalyst; and thermally treating the precatalyst to form the catalyst. |
