Abstract
A method of preparing a catalyst comprising a) drying a chrominated-silica support followed by contacting with a titanium(IV) alkoxide to form a metalized support, b) drying a metalized support followed by contacting with an aqueous alkaline solution comprising from about 3 wt. % to about 20 wt. % of a nitrogen-containing compound to form a hydrolyzed metalized support, and c) drying the hydrolyzed metalized support followed by calcination at a temperature in a range of from about 400° C. to about 1000° C. and maintaining the temperature in the range of from about 400° C. to about 1000° C. for a time period of from about 1 minute to about 24 hours to form the catalyst.
