A method of preparing a catalyst comprising a noble metal supported on alumina characterized by adding an aqueous solution of an aluminum salt that is substantially free of metals other than aluminum to an aqueous solution of ammonium bicarbonate substantially free of metals, maintaining the resulting mixture at a pH between 7 and 9 during substantially the entire process and substantially avoiding all pH in the mixture below 7 or above 9, precipitating the alumina hydrate, heat treating said alumina hydrate at a temperature above about 177º C. but below about 760º C, contact said alumina with water to perform the chemical rehydration thereof, impregnate noble metal on said alumina hydrate, and calcine the alumina hydrate impregnated with noble metal at a temperature between 399º C and 816º C.
