(57) Abstract :
A process for preparing a catalyst comprising depositing a metal on a carrier prepared by: - treating one or more thermally
decomposable materials in particulate form comprising potassium under conditions sufficient to reduce the total quantity of potassium
in the thermally decomposable material, - preparing a mixture comprising the treated thermally decomposable material and a heat
sinterable material, and - heating the mixture to sinter the heat sinterable material and to thermally decompose the treated thermally
decomposable material to form the carrier; the catalyst; a process for preparing an olefin oxide by reacting an olefin with oxygen in
the presence of the catalyst; and a method of using an olefin oxide for making a 1,2- alkanediol, a 1,2-alkanediol ether or an
alkanolamine.
